Faraday paradox revisited,magnetic field rotation question.

Listened to that video.  The most important concept they touched on was that there essentially is no paradox.  Magnetic fields don't spin on their magnetization axis so the disc spinning by itself or spinning along w the magnet are essentiall the same.  Applying the lorentz force to this type device will show you that.  The best take i've seen on this was what Tesla alluded to in his notes on a unipolar dynamo. Although, its kind of surprising that he (Tesla) may have overlooked an effect that he clearly knew about that would allow the creation of brushless type device.  I don't agree with the overunity claim as we know overunity doesn't exist.

Another easy test to prove the magnetic field does not rotate with the magnet around the axis of rotation is to remove the external conduction circuit.

If we place a magnet near a conductive metal disk and move the magnet in any direction it will produce a force on the disk. This is due to the changing magnetic field density generating eddy currents in the conductive disk. However if we rotate the magnet nothing happens and no force is generated on the disk.

In fact I built quite a few magnet levitation devices and used an aluminum plate below the magnet to help stabilize it. The aluminum plate would dampen the motion of the levitated magnet on every axis except rotation which would continue for hours with only a small flick of my finger. I also used this phenomena on the magnetic bearings I built to stabilize them with no drag on rotation as well.

The story of Faraday's paradox is kind of funny. Faraday invented the lines of force concept as a form of notation to make it easier to calculate and visualize magnetic fields. He never meant that the imaginary lines should be taken literally. The lines are similar to other forms of notation like north/south poles, positive/negative polarity or up/down. This happens quite a bit in science where a condition of something or a form of notation is taken out of context over time. So there are no rotating lines of force, they are imaginary and a form of notation.

My research on  this topic continues and I have another question

Why brushless faraday disc motor wont work?

The copper disk is suspended over the magnet, I can solder brushes to the disk - one to the center and the other to rim of the disk and yet no rotation, why? Why everything won't rotate together? (battery + wires soldered to disk).

I know the angular momentum bla bla however, what is going on? the lorentz should push the current in the disc and then the current should push the disc, in other words, the current should rotate with the disc due to lorentz force around B field of the magnet, angular momentum is conserved, yet no rotation when brushes ale soldered to the disc.

DC Plasma can rotate over magnets just fine.

This is the well known brushed version, if you solder the wire and suspend everything on a string it wont rotate

I see Newton's Third Law.
