It would be cool to see ferrofluid in a rotating magnetic field from a 3 phase magnet. Maybe we could visualize the field rotating if the frequency was low enough.
A though just came to me, especially after the AC magnet at the end. With such high speed flipping of the magnetic field, the magnetic particles in the ferrofluid must also be flipping to align to the magnetic field. Does this result in an increase in temperature due to friction with the carrier fluid?
Induction heats metal. This is definitely metal, even if it's oxidized. The whole system heating up (including/mostly the core screws) is probably why he limited to a few seconds per shot.
Induction doesn't heat all oxidized metals. Inductive heating requires delocalized electrons. To test this, I put a Tums (calcium carbonate) into an induction heater and it didn't warm up, even though it contains (oxidized) calcium.
i mean it isn't heating it up that much or that quickly since he literally put his finger in it for a bit after it was running and the only protection he has was latex or nitrile gloves... so even if it does heat it up, it didnt heat it up too quicky or to the point it was too hot for him to keep his finger in it.
Absolutely fascinating! Thank you for sharing. Yes that ferrofluid has to be the messiest stuff on the planet - it's like used engine oil full of metal contaminants, will stain just about anything!
@@moomoocowsly It’s just iron suspended in a lipid. I wouldn’t eat the stuff, or put it in my eyes, but I can’t see any possible health risk. We’ve been handling iron and oil for millennia.
Props to you for your dedication towards science, specially physics. Most people feel averse to physics, but they don't understand that it explains everything around us. How the world works essentially. These videos can have very positive and wonderful effects on young minds, may be even push them to pursue science as they get older. I only have one minor suggestion. Videos will have a greater impact if they explained everyday phenomena. You can also notice this from your views. The ruler trick and the putt putt boat videos got over a million views, because we have all seen these, but never asked ourselves why/how they work.
There are no “lines” in a magnetic field. There is just the field. “Lines” appearing in the ferrofluid are simply created by the aggregate alignment of the ferro-particles in the fluid. This can be proven by doing the metal filing experiment a number of times. The “lines” will be in different places with each test. The “lines” in the filings experiment eventuate because each metal filing is literally turned into a mini-magnet and they are just lining up (meshing) end to end because of the poles aligning with the general field, which is actually a 3D dual toroidal shape, where one torus form the North Pole field and the other forms the south field. In between them is the accretion disk, which also appears in the filings experiment. Check out Ken Wheeler (Theoria Apophasis on RUclips) for deeper magnetism explanations.
Here's a explanation of why the ferrofluid on the spinning magnet plate stops going crazy at high speed and act as if the entire magnet is static but weaker. The entire setup becomes stable because the time scale for "ferrofluid goes from flat to spikey" is significantly longer than the time scale for the magnetic field's period, and the tiny perturbation from each half period becomes insignificant compared to the average. Remember that the force the ferrofluid experience stays the same whether the magnetic field is pointing out of it or into it, and also that for this experiment, that's the only thing that affects the behavior of the ferrofluid. You can verify this by increasing the viscosity of the ferrofluid and watch as the pseudo-stable state form at lower speeds. It's a bit like how you stop getting stuck running your nail over a comb when you do it fast enough, but will when you do it slow. The time scale of the force you push your fingers against the comb pushing your finger deep enough to get stuck is much longer than the time it takes for your nail to go over one tooth and reach the next, so you stop getting stuck as your finger doesn't have time to...get stuck. For the drill, the explanation is similar: it's to do with the time scale of things, but here the exact events are different. In this ferrofluid, the spikes doesn't have time to gain much speed before the magnetic field leave and came back from the other side, pulling it the other way. Still, because the ferrofluid is moving in the same direction as the magnets, it spends a little more time getting pulled in the direction the drill is spinning than the opposite direction, so in theory the speed will still build up a little with each period if the experiment was done in a vacuum and it doesn't fly apart. However there's water, so drag stops it from going at any real speeds. You can verify this by having some kind of marker (a drop of colored ink should do) in the ferrofluid, and you'll see it slowly rotates even when it seems stable, and if you graph the ferrofluid's rotation speed against the drills rotation speed, it'll asymptotically approach a limit towards infinity drill rotation speed.
The problem with ferrofluid is it is not showing the density of magnetic field very well. Also ferrofluid I think is not attracted to a magnet as strong as other magnets. (Centrifugal force can detach ferrofluid from a magnet easily so my guess is that is not a very strong attraction force). Could magnetic or iron dust look different in similar experiments (inside rotating magnetic field)? Thank you for sharing!
Never took as much of an interest in science and physics until I started watching this channel. I'd fly to wherever state he is to take his classes if he was a school teacher
Ferrofluid (self made) on top of a magnetic stirrer. This is what I did as well, back at school. Took it to a science fair, it won me 50€. Several years later, I now have a PhD in chemistry and work for one of the most advanced companies on the globe. Pick your trajectory early and watch where it takes you.
@@cdollar67 I didn't phrase it well. My suggestion was to make some smart decisions early in your life that will benefit you your whole life - even without constant intense work input. Like picking up chemistry for me. Never really worked too hard because this is MY THING from the very beginning. And my degree now gives me every possible freedom I could ask for. Maybe you want to do some sports early on, you'll get an athletes body - and you probably keep it for a long time, because you enjoy doing sports. Maybe you're good at crafts. Or maybe you're super nice around people. It's not always work related, but I do think if you make some smart choices early that also fit you as a person, this "trajectory" will carry you far in life.
Use a tone generator and different frequencies with a electro magnet to see the effect of different wavefoms. Should be a easy setup coil, audio amplifier, and a tone generator phone app.
Hotplate in a vacuum chamber with gallium or tin in a pot if you submerge wood in it would it absorb the metal in vacuum. Wood burns at 300 Celsius. Tin melts at 231 Celsius. It should be possible
Please try sealing liquid ferrofluid in a clear plastic tube arranged in a circle. Then try applying different magnetic fields in an attempt to spin the liquid within the tube.
4:14 that is the most electroboom setup if I've ever seen one. All your missing is for the coil to set on fire or you shocking yourself. Really cool video man!
Given the ferrofluid is made with metal nanoparticles, could you use the rotating magnet setup with the ferrofluid as a polishing device? Given metal is fairly abrasive, I feel like it would be a pretty efficient, well lubricated polishing setup for lower hardness, non-magnetic metals.
The magnetic lines are created by the mass channeling the field and lining itself up. You cannot find a magnetic line in a field, because the field is homogeneous. Mass creates the lines. Then, in order to illustrate a field, lines are used to visualize a gradient, but they are not actually there.
You could easily rotate it with coils placed around and there is a vessel in the middle of them to keep the fluid in a circular form. Like mercury or with a inside ring that one polarity and an outer ring has the nother polarity and like rail guns the magnetic field is genersted by the fluid to move
I didn't understand anything you said, but it was awesome, and very cool. I've been working with magnets for 15 years, and I am amazed at what can be dune with them. I have a 3D printer which allows me to explore new possibilities, more in a physical dynamic. But, what you are doing is cool, however the liquid nitrogen part does not seem like a viable application to energy, and propulsion. Thumbs up, like & subscribe.
Awesome video! So many future applications could come from Ferrofluids. Would be awesome to see it in vacuum so it doesn't have the drag of the brine solution.
I saw one video I think it was modeling of Ferrofluid and they found that you only need to know what is happening on the surface of the fluid for the model and you don't have to worry about the internal volume. The fact the ferrofluid stopped spinning with the magnets is kind of proof of that simulation.
The ACTUAL ODDS of us both being both named the same and meeting at a imagine dragon concert. It was fantastic meeting you! Thank you so much for taking a picture with me.
Awesome, maybe this coul be a way to visualize the rotating magnetic field in a three phase induction motor. Probably it would be more interesting at slower frequency than 50/60 Hz
there are a lot of videos on ferrofluid but all of them just shows what happens when a giant magnet is brought near it (VERY boring) . I was looking of this sort of videos, brings a nice change!
If you put Ferrofluid in a glass jar on something like a potters wheel, My guess: The fluid will make a ring because of centrifugal force. As a magnet is applied, the fluid will gain "height" and resemble a Frisbee ring.
You need to add the ferrofluid in a cyclical machine that spins at at 60,000 RPM , to see an electromagnetic field that will lift the entire thing on the air
I didn't at first understand with the disk that the fluid wasn't flowing until you put your finger in. The Spikes don't stay the same which would mean the fluid would be directionaly flowing, but the spikes are forming and then falling down again once the magnet passed. More like a Piston in an Engine than a Wave.
ive had an idea for a WHILE NOW, of using a spinning ferofluid to create gyroscopic forces/stabilization for flying/underwater vehicles and or spacecraft. using a series of electromagnets and a smart circuit to control them you could make such a device with "zero moving parts" other than the ferrofluid itself that is.
@@vladyslavkorenyak872 electrical current moving around creating a moving magnetic field would achieve the same results, without actually having a spinning mass of magnets. i refer you back to "using a series of electromagnets and a smart circuit to control them" in the OP. it would work SIMILARLY to how "railguns" or "coilguns" operate, just in a loop, instead of linearly, using a smart circuit to turn the magnets on and off in series, automatically in a pattern set up to achieve the speed it is set to "spin" at.
Always fascinating to see what you come up with next. I'm wondering if there's any way of using (some form of) Ferro-fluid to create a very powerful electromagnet... Does what you're doing work in inverse? If you pumped ferro-fluid round & round through a conductor fast enough (eg: a tubular copper ring/or plastic tubing surrounded by a copper wire coil), would it generate a perceptable magnetic field? What if you made of ferro-fluid with liquid Oxygen as the liquid component (or some other extremely cold liquid), would this significantly amplify the effect?
That answers my question from last time about whether the ferrofluid was water-based: No (it looks oil-based, but I don't know whether it is hydrocarbon oil or silicone oil).
it seems to me that these spikes are the physical view of the breakdown of a magnetic field. because magnetic fields break down Distance Squared. what would be interesting to see is this fluid is if you can find a magnetic field design that would allow for A spike, any spike for that matter is go beyond the distance squared, another major question i have is what is the capacitance of this fluid for given volume? this should be dependant on the amount of ferral material contained. with this capacitance reading, you can tell if it would be possible to use tesla's theory of harmonics. which is, every body has a harmonic state, and when that hormonic state is achieved, it becomes a storage unit for that energy, given enough of these harmonic unites of stored energy stops and releases this energy, you would achieve a very large spike of energy the moment its released. tesla also showed us that anytime you have a capacitive substance between 2 plates, that you can affect that substances harmonics with energy, and you can draw energy off of it at a given rate. this is known as capacitence.
Oh, how much fun that must have been! You should definitely try this with a polyphase arrangement of coils and a variable frequency! Just like an induction motor, but with the ferrofluid as the rotor. ;)
Next experiment should include AC current a various frequencies. Perhaps even to sources at different locations so they can oscillate in and out of phase.
If we put ferrofluids in a container surrounded by magnets, maybe we could control it and give it any shape and animation we want to it. That would be even more amazing.
The ferrofluid at the beginning of the video not only looks like CGI; it looks like bad CGI, like they didn't put enough effort into making it look real. It's just such an unusual thing, not similar to anything else we experience in daily life, that it's hard to comprehend what we're seeing.
It looks like two black hole colliding together
