    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.

    • @BrandonSchabes
      @BrandonSchabes 2 года назад

      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.

    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.

    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.

  • @jeeeeeeeeeeezus
    @jeeeeeeeeeeezus 2 года назад +10

    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!

    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.

    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.
