Faraday paradox revisited,magnetic field rotation question.

[PolaczekCebulaczek]

right... but lets stay on topic.

Im still struggling with electroscope experiment, electronic FET based electroscope is very sensitive, led is flashing when antenna is near motor so i need long shaft for magnet so fet wont pick up any E field coming from motor coil.

meanwhile...

I will never fully understand why when i move already moving electron it suddenly emits E field, its because i slowed electron speed?
In permanent magnet, electrons are moving, not like in wire but since they are moving so there is b field.
What about vacuum tube? is the e field there? i guess there is because electron beam will curve when charged plate is near it.Sooo when coil is wrapped around vacuum tube, a current is induced in that coil?

Maybe you could just spin the magnet while hanging it from a string?

The electroscope would need to show charge while the magnet is spinning one direction and nothing while spinning the other direction to be a valid confirmation since your electroscope will show charge in only one direction.

Or we could levitate it and spin it up to an absurd RPM with no friction like I did with my device in the picture below. The bottom plate is 3/8" thick aluminum to stabilize the magnet and as we know there is no drag on the axis of rotation.

easy to say... magnet will wobble all over the place, it has to be perfectly stable rotation no orbiting or wobbling
the levitation sounds like awesome idea.

how did you levitate it? levitron stuff?

That's a good idea, but could you just as easily spin it on a string over the aluminum plate to stabilize it?

Find a wooden dowel to fit in a ring magnet and center a string in the dowel then wind up the string and as it unwinds over the aluminum plate it should be stable.

The aluminum plate may however mask another condition that may exist where the plate causes the field to become stationary and instead slip in the gap between the magnet and the plate.

That is why I originally thought suspended only from a string.
