Anyone else find it strange that we are shown this thing that exists in real-life yet the top comments all mention how cool it is relative to fictional things (most, if not all, of which were created after this real-life thing)?

Not really, that's the way it goes. We must first conceive of something before we can realise it in actuality. Look at the tablet computers in Stanley Kubrick's 2001:Space Odessa for example, somebody had to imagine them for somebody to be able to make them. Not to mention ferrofluid was invented in '63, way before the subjects of the comparisons drawn in the top comments.

It makes sense, sci-fi usually comes up with ideas before actual discoveries / inventions make them possible. Like we see hover boards in back to the future, androids in blade runner, etc.
So when those things (or something similar) is made it reminds us of the familiar fictional version. In this case the X-files black liquid or Spiderman's Venom symbiote.
Right but these things that are mentioned were made after 1963.

Well in this case it's just a obscure science phenomenon that not many people have seen, even if it is an old discovery it's probably "new" to most seeing it here. People connect to things they're familiar with when they see something new to them. Ever hear a kid call a cat a dog? If they haven't seen a cat, they think of the thing most similar. In this case the magnetic liquid is similar to some popular sci fi concepts.

Because the applications in the make believe worlds are cool. The application in real life is a drop of black liquid trapped in a jar that only does one thing and it only does that one thing when you put a magnet near it.

They're also closely related to magnetorheological fluids, which are essentially fluids where the viscosity can be altered using a magnetic field. There's been a lot of research into using them for dampers, biomaterials, frictionless clutches etc.

YES I CAN!
I work with this stuff! One of its uses is in a process called Magneto-rheological finishing (MRF) in the optics industry.
With precisely controlled magnetic fields, and the right additives (polishing compounds) it can be used to achieve surface accuracy on lenses and other optics that simply cannot be achieved, economically, through conventional means.
The level of accuracy this stuff can reach in ten minutes is astonishing. I'm talking 12 nanometers of variance. The stuff is awesome.
Of course the equipment to use it costs $500,000 or more... But if your clients are big laboratories and/or NASA/JPL then it's a worthwhile investment.
I have a quick question you may be able to answer!
The bumps or spikes in the gif.. Would those each represent a flux line? I noticed as the magnet gets further away less bumps form.. Would that be due to the flux density decreasing over distance?
EDIT: clarity

Daiwa, a fishing reel manufacturer, uses this product or something similar in some of their reels to create a better seal against salt and corrosion. They label it as "Mag Sealed Technology" and like to reflect that in the price.
I researched the iron oxide nanoparticles that typically make a ferrofluid. Basically, these iron oxide nanoparticles are superparamagnets meaning they have no remnant magnetization (are not magnetized) without a magnet being present. This is why when he moves the magnet away the ferrofluid falls. Superparamagnets have a ton of really cool applications.
My PhD research (Nanoscience and Nanotechnology) consisted of making iron oxide nanoparticles and coating them for use as a cancer therapeutic. These superparamagnets can be used in an AC magnetic field to give a patient hyperthermia treatment (think of burning up cancer cells). The iron oxide is very useful in biomedical applications as it is biodegradable, meaning the body will naturally metabolize iron.
The end product I made was an iron oxide nanoparticle with a coating for biological stability, with capability of being further coated with targeting ligands or chemo/radiation treatment. We were successfully able to add a radioactive metal to provide both the hyperthermia treatment from iron oxide and radiation treatment from the radioactive metal.

It's not water though, OP ( u/stchy_5 ), it's some form of transparent liquid, probably an oil that's less dense than the ferrofluid.

That what I thought since the ferro is moving much slower than it would in water.
If fluids with different densities are miscible it's very hard to keep them separate. Try pouring a layer of fresh water dyed green over a layer of denser salt water dyed red. Unless you take extreme precautions you'll get a cup of brownish water.

Fun fact. They have these in the shocks of my car. Using electricity they can change the viscosity of the fluid in the shocks to make them more stiff or softer on the fly. It's one of the things GM actually developed and licenses out to other companies like Ferrari.

Handling and comfort characteristics. For handling in general you want a stiffer suspension to prevent body roll. This often leads to a rougher ride though and you feel more of the road which sucks for just cruising around.
The neat thing about the newer generation of these systems is that it reads the road conditions many times a second and adjusts the stiffness of each shock accordingly to minimize body roll.

What frustrates me is I just went out and bought ferrofluid off amazon since it's relatively inexpensive, but I can't figure out what medium to use in the bottle so it free flows but doesn't end up getting stuck on the side in the bottle, breaking down, or discolouring the medium.

Hey there. When I made mine I put it in blue Windex and that worked for awhile. Although like you said after about a year or two it started to loose its liquid like properties

I have a few questions, if you don't mind, since you seem to be experienced in this. Can you make multi-colored ferrofluid? Can you use different densities of fluids with different colors for the medium while still allowing the ferrofluid to free flow? If yes to both those questions, can you make a combination of multi-colored ferrofluid inside a medium of fluid that has a variety of densities and colors? Thanks for taking the time to answer!

Thank you for the answers so far! I have another though, which continues on from the previous...
Is it possible to craft a specialized magnet that would cause the ferrofluid inside the container to form itself into a specific shape?
Basically, with all the previous possibilities your answers have allowed for, could someone feasibly create a multi-colored fluid filled bottle with ferrofluid inside and a magnet attached to backside so that it forms the image of, for example, the variant German flag which includes the coat of arms? https://en.wikipedia.org/wiki/Flag_of_Germany#/media/File:Flag_of_Germany_(state).svg

Could you imagine if done right that it could be profitable? Thank you in advance.

I made my own ferrofluid bottle when I was 11. I got the ferrofluid off Amazon and had magnets come with it. But I didn't know you needed a special suspension liquid, because I just used water. Within a few months, it became murky and started to break apart. I haven't made it again since.
I tried that (even using RODI water) and it ended up discolouring/disforming/sticking over time. I have too much ferrofluid to just give up. Plus any ferrofluid toy that's not crazy expensive it usually tiny.
Would it be possible to start the ferrofluid itself from iron powder in oil, and floating that in an alcohol solution? since oil and alcohol don't mix I wonder if it'll keep it contained

Polysorbate as a surfactant lasts a while in water. Alcohol works but tends to dissolve the ferrofluid. Scotchguard to coat the glass extends the shelf life also. I used to sell these on eBay at the $10 price point. Happy to help out if you really want to make it.
I'm definitely interested. I'm looking for somewhat inexpensive (less than $50) and readily obtainable ingredients. I'd prefer not to require government clearance to purchase them.

That's a pretty good idea. I'd personally go with a pi 0 just so the computer is of a comparable size to what it's running, but if you hooked up an electromagnet (or a chunk of iron and some wire) to the pi/arduino, it should work fine. Not sure how easily you can find an electromagnet for diy projects though.

Could you encapsulate a couple drops in something more like a gel so it has the same density and magnetic properties but stays in its own separate drop (eg orbitz soda) and color those two drops white, so you could give your ferrofluid googly eyes?
Essentially it's mineral oil, industrial detergent and iron shavings. It also costs more than top shelf scotch.

How exactly would you mix your drinks with this? The ferrofluid doesn't exert much force on the liquid around it. Magnetic stirrers are a thing, but you use a solid ferrous object rather than loose ferrofluid.

And some more options here, including a skull-shaped bottle.
I'd totally recommend this product for anyone who thinks that GIF is fun/interesting. And the GIF doesn't even scratch the surface of what you can do with this bottle. If you rapidly agitate the fluid with a magnet, it basically vaporizes the black stuff, which then lets you "vacuum up" the cloud using the magnet. And if you get two strong magnets you can create a sort of tug-of-war between them. Or a funny anti-tug-of-war if the poles are opposed. If you have a variety of magnet sizes & shapes, you can quickly learn a lot about the field lines' properties. There are surprising differences between the field from a small, strong magnet vs. a tall stack of less-powerful magnets. A great piece of entertainment that is both artistic and educational.

I think I'll just stick to enjoying the gif for free.
I just had a great idea that others probably already had.
Ferrofluid pets.
They would be in one of those ant tanks only with water (or some kind of solution) with a panel on the back that has a magnet on the other side. The magnet would semi randomly move around the tank with varying levels of magnetic pull (or just closer or further from the panel). Anyway you could have a sensor so that normally it is on a low movement setting, but it would react to people being near it or walking past.
For bonus points there is a sensor that knows where you put your finger on the glass (or plastic) so that the "pet" will go to your finger if you touch the case.
If someone makes this and I can buy it for under $500 consider me sold.
The field lines as u/Tod_Gottes says is what makes it spiky when it comes in close contact with the magnet. The ferrofluid can be made out of superparamagnetic iron oxide nanoparticles. This means that without the external magentic force the ferrofluid does not exhibit any magnetism. The superparamagnetic iron oxide nanoparticles can have very strong (relative) magnetism when an external magnetic field is applied.

So then does this mean the magnet and the ferrofluid are in love?
I believe the spikes are a due to the properties of the fluid, such as the viscosity/coheasion/adhesion, more than they are about the flux field. The magnetic field would be uniform/smooth/non-spikey.

They were a bit rusty when they first got back together.
The iron would be degraded by the body. The iron oxide nanoparticles that make the ferrofluid are not typically magnetic in the absence of a magnetic field (superparamagnetism) so unless you had an insanely strong magnet it would just get degraded. Now the surfactant coating the iron oxide that makes it soluble in an oil might be toxic ( oleic acid and oleylamine are very common)

Yes, there are several applications. Hard drive mechanical properties, etc. I researched the iron oxide nanoparticles that typically make a ferrofluid for treatment of cancer. They can be used as a MRI contrast agent, provide hyperthermia (burn up cancer) treatment, and can be covered with additional chemotherapeutics, radio therapeutics, or diagnostic chemicals. Plus iron oxide is typically biodegradable.

Typically the iron (ferro-) is most soluble in an organic solution like an oil. That's what gives it the fluid properties. The concentration has to be high enough that the iron holds the oil/fluid together when the iron responds to magnetic field.

We had the exact same thing in one of the labs I worked in as an Undergraduate. While I waiting for my experiment to run I would shake it the bottle really hard for awhile so the ferrofluid would break into very tiny droplets and spread around the container. Then place a strong magnet next to it and watch as the ferrofluid seemed to appear out of nowhere on the magnet.

Made some of this in my garage once. It's pretty neat. All you need are ferrous shavings and motor oil. The downside is that without an emulsifier, the shavings will suspend out of the oil, so you only get about 10-15 seconds of play time before it's separated out. Still fun

Can anyone explain why it tends to form spikes? I would expect all the particles to get as close as they can to the magnet, but I guess the fluid is interacting with itself somehow?
TIL: A ferrofluid (portmanteau of ferromagnetic and fluid) is a liquid that becomes strongly magnetized in the presence of a magnetic field. Ferrofluid was invented in 1963 by NASA's Steve Papell as a liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field.
my mind looks at things like this and wonders if there could be any practical application. The first thing i thought was a liquid switch for a multi chemical bomb....can some one give me a practical and less horrific application.
I had a 20 year old pair of B&W speakers that used this as a cooling fluid for the tweeters. It was all dried up and next to impossible to get out of the tweeter, because now it was magnetic dust!

I need to know the logistics of somehow getting this in a open loop water cooling system of my PC. Considering its pumping water I'm guessing it won't really work but if anyone has an idea it'd be cool to hear it. Maybe keep it in place with a magnet or just have it in the reservior or maybe a dummy reservior next to the actual one being pumped that's got a lot of this and some sort of programmed pattern for the magnet to move with.

Entrancing, even though I realize its just molecules reacting to a magnetic attraction, there is something rather "life-like" about the way the particles behave.
RooGang ยท 1 points ยท Posted at 22:42:04 on September 26, 2016 ยท (Permalink)
I could imagine setting up a powerful electromagnet inside of some kind of sphere, then dangling that sphere in a large pool of water with a bunch of this stuff in it. Do it in a lab setting with clear walls around the pool of water and have a way to measure and modulate the strength of the magnet, and you would be able to see the physical representation of the electromagnetic force in 3D. Well, you'd only be able to see the surface area of it unless you had some method of penetrating the outermost layer of ferrofluid.

I have one of these, if anyone is interested in more you can find this product on Vat19, it's called 'Ferrofluid in a jar' I believe. About $28 I do so believe.
Ferro fluid are tiny iron particles coated with a detergent so they don't clump suspended in a mineral oil. The ferrous particles are attracted by magnetic fields but too small to break the surface tension of the mineral oil.
The result is that the entire fluid distorts to follow magnetic flux lines.
Yep, one of the most common ways of making this is in oleic acid and oleylamine. The oleylamine (detergent or surfactant) coats the iron oxide nanoparticles and makes it soluble in organic oils. Get it concentrated enough and you have a ferrofluid.

Could you make energy with this, with hydro electric power?
Place magnet on top of large water column, ferro-fluid would move up through the water, then turn off the magnet and let gravity take over to create energy.

I suppose you could store energy with this. But you couldn't create energy with this. There are easier ways to pump water (well, liquids) uphill that don't require ferro-fluid.
Not really. Ferro fluid is a suspension of iron particles coated with detergent so they don't clump, suspended in a mineral oil.
The iron particles respond to magnetic fields but they're not big enough to break the surface tension of the mineral oil. So the entire fluid distorts in response to magnetic fields.
The iron in your blood is significantly smaller and the concentration much less for it to respond to magnetic fields like this.
[deleted] ยท 0 points ยท Posted at 18:09:28 on September 26, 2016 ยท (Permalink)
It's not suspended in water. The tiny particles in ferro fluid mean the stuff stains horribly. If you used it without a suspension fluid, it would just stain the glass brown wherever the fluid touched it.
Can't use water because that'll just turn into a very fine emulsion over time as the ferro fluid breaks up. It's some kind of detergent mixture that repels the ferrofluid.

Not really, that's the way it goes. We must first conceive of something before we can realise it in actuality. Look at the tablet computers in Stanley Kubrick's 2001:Space Odessa for example, somebody had to imagine them for somebody to be able to make them. Not to mention ferrofluid was invented in '63, way before the subjects of the comparisons drawn in the top comments.

It makes sense, sci-fi usually comes up with ideas before actual discoveries / inventions make them possible. Like we see hover boards in back to the future, androids in blade runner, etc.
So when those things (or something similar) is made it reminds us of the familiar fictional version. In this case the X-files black liquid or Spiderman's Venom symbiote.

Well in this case it's just a obscure science phenomenon that not many people have seen, even if it is an old discovery it's probably "new" to most seeing it here. People connect to things they're familiar with when they see something new to them. Ever hear a kid call a cat a dog? If they haven't seen a cat, they think of the thing most similar. In this case the magnetic liquid is similar to some popular sci fi concepts.

Because the applications in the make believe worlds are cool. The application in real life is a drop of black liquid trapped in a jar that only does one thing and it only does that one thing when you put a magnet near it.

They're also closely related to magnetorheological fluids, which are essentially fluids where the viscosity can be altered using a magnetic field. There's been a lot of research into using them for dampers, biomaterials, frictionless clutches etc.
TheSecretMe ยท 13 points ยท Posted at 16:46:26 on September 26, 2016 ยท (Permalink)
A far more common use for it is as a dust seal in electronics parts. Basically this is a fluid that can be controlled with a magnetic field.
Computer hard drives for instance us small amounts of ferro fluid to form a liquid seal against dust around the shaft that spins the harddrive.
They can also be used to form seals that open and close without any moving parts. Just move the fluid by turning electromagnets on and off.

Also they are becoming increasingly common in suspension systems for high end sports cars.

YES I CAN!
I work with this stuff! One of its uses is in a process called Magneto-rheological finishing (MRF) in the optics industry.
With precisely controlled magnetic fields, and the right additives (polishing compounds) it can be used to achieve surface accuracy on lenses and other optics that simply cannot be achieved, economically, through conventional means.
The level of accuracy this stuff can reach in ten minutes is astonishing. I'm talking 12 nanometers of variance. The stuff is awesome.
Of course the equipment to use it costs $500,000 or more... But if your clients are big laboratories and/or NASA/JPL then it's a worthwhile investment.

I have a quick question you may be able to answer!
The bumps or spikes in the gif.. Would those each represent a flux line? I noticed as the magnet gets further away less bumps form.. Would that be due to the flux density decreasing over distance?

I researched the iron oxide nanoparticles that typically make a ferrofluid. Basically, these iron oxide nanoparticles are superparamagnets meaning they have no remnant magnetization (are not magnetized) without a magnet being present. This is why when he moves the magnet away the ferrofluid falls. Superparamagnets have a ton of really cool applications.
My PhD research (Nanoscience and Nanotechnology) consisted of making iron oxide nanoparticles and coating them for use as a cancer therapeutic. These superparamagnets can be used in an AC magnetic field to give a patient hyperthermia treatment (think of burning up cancer cells). The iron oxide is very useful in biomedical applications as it is biodegradable, meaning the body will naturally metabolize iron.
The end product I made was an iron oxide nanoparticle with a coating for biological stability, with capability of being further coated with targeting ligands or chemo/radiation treatment. We were successfully able to add a radioactive metal to provide both the hyperthermia treatment from iron oxide and radiation treatment from the radioactive metal.

It's not water though, OP ( u/stchy_5 ), it's some form of transparent liquid, probably an oil that's less dense than the ferrofluid.

It can't be oil because that would dissolve the ferrofluid. It must be some kind of polar solvent, others in this thread mentioned isopropyl alcohol.

As long as they have different densities, wouldn't they stay separate? The ferrofluid is also a type of oil.

If fluids with different densities are miscible it's very hard to keep them separate. Try pouring a layer of fresh water dyed green over a layer of denser salt water dyed red. Unless you take extreme precautions you'll get a cup of brownish water.

Handling and comfort characteristics. For handling in general you want a stiffer suspension to prevent body roll. This often leads to a rougher ride though and you feel more of the road which sucks for just cruising around.
The neat thing about the newer generation of these systems is that it reads the road conditions many times a second and adjusts the stiffness of each shock accordingly to minimize body roll.

What frustrates me is I just went out and bought ferrofluid off amazon since it's relatively inexpensive, but I can't figure out what medium to use in the bottle so it free flows but doesn't end up getting stuck on the side in the bottle, breaking down, or discolouring the medium.

With the exception of saying that it's not for use in loudspeaker applications.

I have a few questions, if you don't mind, since you seem to be experienced in this. Can you make multi-colored ferrofluid? Can you use different densities of fluids with different colors for the medium while still allowing the ferrofluid to free flow? If yes to both those questions, can you make a combination of multi-colored ferrofluid inside a medium of fluid that has a variety of densities and colors? Thanks for taking the time to answer!

Thank you for the answers so far! I have another though, which continues on from the previous...
Is it possible to craft a specialized magnet that would cause the ferrofluid inside the container to form itself into a specific shape?
Basically, with all the previous possibilities your answers have allowed for, could someone feasibly create a multi-colored fluid filled bottle with ferrofluid inside and a magnet attached to backside so that it forms the image of, for example, the variant German flag which includes the coat of arms? https://en.wikipedia.org/wiki/Flag_of_Germany#/media/File:Flag_of_Germany_(state).svg

Lastly, one final question: Let's say that an item such as the one we have begun to describe was crafted, a ferrofluid inside a bottle/vial/etc, and you could choose from a variety of designs like coat of arms, or flags, and other interesting images, and that it allowed for you to shake it up and watch as it settles back down to the original form, do you think that this would be a marketable item, could you imagine seeing this product selling in stores? Could you imagine if done right that it could be profitable? Thank you in advance.

vegetable oil isnt a bad idea. The particles are coating in long greasy molecules, so they like oil. The water and oil should stay seperate (obviously).

It's because oils are non polar and hydrophobic coatings are also non polar to repel h20 which is a polar molecule, but then I had a science degree from the 80's so what do I know.

That's a pretty good idea.

Not sure how easily you can find an electromagnet for diy projects though.

And some more options here, including a skull-shaped bottle.
I'd totally recommend this product for anyone who thinks that GIF is fun/interesting. And the GIF doesn't even scratch the surface of what you can do with this bottle. If you rapidly agitate the fluid with a magnet, it basically vaporizes the black stuff, which then lets you "vacuum up" the cloud using the magnet. And if you get two strong magnets you can create a sort of tug-of-war between them. Or a funny anti-tug-of-war if the poles are opposed. If you have a variety of magnet sizes & shapes, you can quickly learn a lot about the field lines' properties. There are surprising differences between the field from a small, strong magnet vs. a tall stack of less-powerful magnets. A great piece of entertainment that is both artistic and educational.

I just had a great idea that others probably already had.
Ferrofluid pets.
They would be in one of those ant tanks only with water (or some kind of solution) with a panel on the back that has a magnet on the other side. The magnet would semi randomly move around the tank with varying levels of magnetic pull (or just closer or further from the panel). Anyway you could have a sensor so that normally it is on a low movement setting, but it would react to people being near it or walking past.
For bonus points there is a sensor that knows where you put your finger on the glass (or plastic) so that the "pet" will go to your finger if you touch the case.
If someone makes this and I can buy it for under $500 consider me sold.

Field lines. Its because each iron piece magnetizes the next and they arrange themselves in the same orientation. The field is everywhere, but it does have an orientation. https://en.m.wikipedia.org/wiki/Magnetic_field#/media/File%3AMagnet0873.png
That picture is more filled in and 2d.
To clarify though, the field itself isnt spiky. Thats just the most stable shape the iron fillings can make when inside the magnetic field.
https://en.m.wikipedia.org/wiki/Vector_field Imo thats a better visualization of the field.

Why do the spikes get more prominent but fewer in number as the magnet is moved farther away from the fluid?
Wildslayer66 ยท 1 points ยท Posted at 20:23:55 on September 26, 2016 ยท (Permalink)
The field lines as u/Tod_Gottes says is what makes it spiky when it comes in close contact with the magnet. The ferrofluid can be made out of superparamagnetic iron oxide nanoparticles. This means that without the external magentic force the ferrofluid does not exhibit any magnetism. The superparamagnetic iron oxide nanoparticles can have very strong (relative) magnetism when an external magnetic field is applied.

I believe the spikes are a due to the properties of the fluid, such as the viscosity/coheasion/adhesion, more than they are about the flux field. The magnetic field would be uniform/smooth/non-spikey.

The iron would be degraded by the body. The iron oxide nanoparticles that make the ferrofluid are not typically magnetic in the absence of a magnetic field (superparamagnetism) so unless you had an insanely strong magnet it would just get degraded. Now the surfactant coating the iron oxide that makes it soluble in an oil might be toxic ( oleic acid and oleylamine are very common)

Yes, there are several applications. Hard drive mechanical properties, etc. I researched the iron oxide nanoparticles that typically make a ferrofluid for treatment of cancer. They can be used as a MRI contrast agent, provide hyperthermia (burn up cancer) treatment, and can be covered with additional chemotherapeutics, radio therapeutics, or diagnostic chemicals. Plus iron oxide is typically biodegradable.

I feel that a big bottle of this and a few more magnets would pair quite nicely with a dose of LSD.
Edit: another tried and true pairing is a big glass tabletop, glow-in-the-dark markers, and a little baby oil. Turn off all the lights except for a blacklight and your trip just turned you into a mondo artistical magician.

Typically the iron (ferro-) is most soluble in an organic solution like an oil. That's what gives it the fluid properties. The concentration has to be high enough that the iron holds the oil/fluid together when the iron responds to magnetic field.

Most likely similar to mixing oil and water you would get tiny droplets of ferrofluid a that would reform into a large one as they are happier with themselves rather than being an emulsion.

Wildslayer66 ยท 1 points ยท Posted at 19:21:03 on September 26, 2016 ยท (Permalink)
Yes, basically the magnetic bits are typically iron oxide (ferro for iron) that is very well or perfectly dispersed in an oil
The ferrofluid also works in air and will climb the side of container in response to a magnet.

We had the exact same thing in one of the labs I worked in as an Undergraduate. While I waiting for my experiment to run I would shake it the bottle really hard for awhile so the ferrofluid would break into very tiny droplets and spread around the container. Then place a strong magnet next to it and watch as the ferrofluid seemed to appear out of nowhere on the magnet.

Made some of this in my garage once. It's pretty neat. All you need are ferrous shavings and motor oil. The downside is that without an emulsifier, the shavings will suspend out of the oil, so you only get about 10-15 seconds of play time before it's separated out. Still fun

TIL: A ferrofluid (portmanteau of ferromagnetic and fluid) is a liquid that becomes strongly magnetized in the presence of a magnetic field. Ferrofluid was invented in 1963 by NASA's Steve Papell as a liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field.

I need to know the logistics of somehow getting this in a open loop water cooling system of my PC. Considering its pumping water I'm guessing it won't really work but if anyone has an idea it'd be cool to hear it. Maybe keep it in place with a magnet or just have it in the reservior or maybe a dummy reservior next to the actual one being pumped that's got a lot of this and some sort of programmed pattern for the magnet to move with.

I could imagine setting up a powerful electromagnet inside of some kind of sphere, then dangling that sphere in a large pool of water with a bunch of this stuff in it. Do it in a lab setting with clear walls around the pool of water and have a way to measure and modulate the strength of the magnet, and you would be able to see the physical representation of the electromagnetic force in 3D. Well, you'd only be able to see the surface area of it unless you had some method of penetrating the outermost layer of ferrofluid.

Ferro fluid are tiny iron particles coated with a detergent so they don't clump suspended in a mineral oil. The ferrous particles are attracted by magnetic fields but too small to break the surface tension of the mineral oil.
The result is that the entire fluid distorts to follow magnetic flux lines.
Wildslayer66 ยท 1 points ยท Posted at 19:44:13 on September 26, 2016 ยท (Permalink)
Yep, one of the most common ways of making this is in oleic acid and oleylamine. The oleylamine (detergent or surfactant) coats the iron oxide nanoparticles and makes it soluble in organic oils. Get it concentrated enough and you have a ferrofluid.

Could you make energy with this, with hydro electric power?
Place magnet on top of large water column, ferro-fluid would move up through the water, then turn off the magnet and let gravity take over to create energy.

I suppose you could store energy with this. But you couldn't create energy with this. There are easier ways to pump water (well, liquids) uphill that don't require ferro-fluid.

Not really. Ferro fluid is a suspension of iron particles coated with detergent so they don't clump, suspended in a mineral oil.
The iron particles respond to magnetic fields but they're not big enough to break the surface tension of the mineral oil. So the entire fluid distorts in response to magnetic fields.
The iron in your blood is significantly smaller and the concentration much less for it to respond to magnetic fields like this.

It's not suspended in water. The tiny particles in ferro fluid mean the stuff stains horribly. If you used it without a suspension fluid, it would just stain the glass brown wherever the fluid touched it.
Can't use water because that'll just turn into a very fine emulsion over time as the ferro fluid breaks up. It's some kind of detergent mixture that repels the ferrofluid.
