Latest: No back torque generator.

@ Broli,

In the case where the disk and magnet rotate together, the disk is simply a conductor in the same frame as the magnet and is not breaking any lines of force and all the current is generated in the external conductors that are being cut by the rotating magnet. This is 0% on disk 100% from external circuit.
The faster the magnet and disk rotate, the more is generated.

According to you, the size of the disk would be irrelevant since it is simply a conductor in the same frame as the magnet and is not breaking any lines of force.

So, a 24 inch diameter magnet with a 1 inch diameter disk would generate the same amount of current as a 24 inch diameter magnet with a 24 inch diameter disk when they rotate together?

If there is current flowing in the disk, then that current will be cutting through the lines of force.  I don't think the external circuit is 100% and the disk is 0% like you said.

Just a thought.

Lumen I already know all the results you mention. You seemed to have missed what I asked you.

I told you to spin both magnets and conductor together and use an electrostatic compass near the rim of the disk. This will show you whether the rim is more negatively charged or positively charged due to electrostatic induction. You can probably use a different method to show it as well. But if this is the case then this proves the EMF on the plate caused the charge gradient right?

Doing the experiment that I suggested with the different size disks and same size magnet, would also prove the EMF on the plate caused the charge gradient and not the external circuit.

GB your experiment makes sense if you already accept that the EMF is caused on the disk. But I'm sure lumen has a reason why this is not the case, even though it's as clear as black and white.

I tried to measure something with my prototype by holding it and spinning myself with a voltmeter in my hand - imagine how that looked like: Dancing with magnets

Anyway, my voltmeter can measure as low as 1 mV, but I did not see anything on the voltmeter. Now I have very few turns, only 10 or so, but very strong magnets. I tried to flip the magnet from side to side like wipers on a car, but faster, and could not measure anything in both AC or DC on the voltmeter. However, if I moved the coil back and forth over the same magnets, I measured up to 5mV.

This means the wire has to cross the magnetic lines in order to get a measureable result. I cannot confirm if there is voltage indicated below 1mV in @brolis setup or not, as my voltmeter cannot measure anything below 1mV.
