Faraday paradox revisited,magnetic field rotation question.

[PolaczekCebulaczek]

ok but when magnetic field is moving trough space it produces inducted electric field right? according to Faraday, charged test charge should experience a force near spinning magnet like so:

so field is moving with magnet but no induction in stationary disk??

lenz is lenz ,lorentz is lorentz but there should be non zero current detected in disk.

  In the case of something like the speedometer there are "Small rotating eddies"
  set up within the disc.

Once you consider all the cases of a Faraday generator you will see the problem.

How about: Magnet stationary but disk and contact spinning = no charge?

Then you see it's only the difference between the disk and contact that matters.

The magnet makes no difference if it rotates or not. Why is that?

It's because the uniform field of a magnet on it's axis will remain stationary OR rotate whichever produces no work.
It's only when the field is trapped between a rotating disk and stationary conductor OR stationary disk and rotating conductor that the field must cut through one or the other objects and work is performed.
It is in fact forced to cut through the conductor or disk the same as a normal generator uses the force of the magnet itself to push it's field through a conductor.

he magnet makes no difference if it rotates or not

but what about electric field detection when magnet is spinning by test charge near it? its there or not?

The charge will exist the same as if the detector were rotating around a stationary magnet.
A charge separation exists when something moves through a magnetic field even if the field is of constant intensity.
If a current flows then there is resistance to the movement, unless the field is constant in which case the field is pushed along to prevent current flow.
If the uniform field is trapped between two conductors and is forced to cross one or the other, then again the current causes increased resistance.

In any case you need to be careful not to cross the field twice as the field is circular and the return of the field through the conductor will cause a charge in the opposite direction and cancel any effect.

Maybe do some experiments and see what you discover.
