Faraday paradox revisited,magnetic field rotation question.

[lumen]

All the information here is old and there is no reason to try it again thinking there could be different results.

I thought the new test was to build a super sensitive electroscope using a mosfet so we could detect any rotation of the magnetic field without any contact to the rotating magnet rather than simply repeating the old brush and disk controversy that adds nothing to the understanding of what's really going on.

In theory the rotating field would cause and uneven distribution in the probe and should be able to trigger the detector if the probe was already preset to only a few millivolts from triggering.

  Now that I understand the  Faraday-Paradox  not only do I see how correct it is,  I also now understand various other widely-accepted concepts in mainstream physics,  that is :
    - a magnet cannot function without the medium,  it's magnetic field will not be present without the medium
    -  this also links with the  curie-point of magnets,  imagine a magnet floating so far away from the universe that there is insufficient medium for it to have a magnetic-field,  which it could not produce anyway,  because it would be too frozen.
________

    Now I wonder what about radiation( light etc ),  what happens to light when it travels sufficiently far away from the universe,  does the lack of the medium somehow slow it down( or physically change it ),  causing it to somehow fall back to the universe,  and when it's back in the medium it's 'rehydrated' or something.
______

   My idea of using the RPM comparison to test the  Faraday-Paradox,  that is very very feasable
      -  You could encase coils, windings, or permanent-magnets in Solid-Plastic,  so they themselves would never experience any air resistance
      -  And theres so many different types designs of electric-motors which do cause rotation,  even though the device looks nothing like an electric-motor,  for example they have no coils/windings

   I don't know if the photo of the Magnetic-Levitation posted on this thread is   Non-Electric-Permanent-Magnet-Full-Levitation( visually contravening Earnshaw's-Theorem ),  or electromagnetic-levitation.

    What is the barrier to people posting photos/videos of   Non-Electric-Permanent-Magnet-Full-Levitation( visually contravening Earnshaw's-Theorem ) on the internet,   it is actually still within Earnshaw's-Theorem( and theory of magnetic-levitation ),  it is actually mentioned ( unclearly, and badly ) right on the wikipedia pages of both  Earnshaw's-Theorem and   Magnetic-Levitation ,   so obviously your not contravening any laws of physics,  there should be no reason for suppression

I just ordered some magnets for final experiment.

meanwhile..

this probably has been discussed 100 of times but once again for sake of this topic:
Would a magnet like this rotate if current flows in wire ?
What will happen if compass is inside the ring?

Would have to be individual mags to make the ring, if it did work. Like the paradox, the field of the mag you show would have the same non effect as putting current through the copper disk trying to spin the ring magnet. It wont spin, but the copper disk will.

I like this experiment because a single conductor generates a special circular field that should cause the magnet to spin.
In the Faraday paradox there are only three things that are actually going on:

1: When the magnet spins with the disk, the disk serves only as a conductor and current is generated from the flux cutting the brush/external conductor.
2: When the magnet is stationary, the disk is cutting the field as it rotates and the brush is only a conductor.
3: The uniform field is another special case and can have the effect of sliding because the field is of the same magnitude will do no work by sliding.

It is number "3" that your experiment is testing and is likely that it will NOT rotate if number "3" is true in which case the Faraday generator is trapping the uniform field between two conductors and forcing it to cut either the disk or the brush/conductor in which case it would actually be cutting both as 1/2 rate.
