Faraday's unipolar generator

During the holidays, I experimented a bit with a variation of the Faraday unipolar generator from another one of Meyl's papers:

Basically, a rotating permanent magnet, with one brush at the axis, and another one at the outer rim of the magnet. I re-used some pieces from a previous generator experiment.

Despite the fact that I tried it at a rather miniature scale (magnets of either 1 cm or 2 cm diameter), I got an output voltage which depended on magnetic field strength and magnet diameter according to Faraday's induction law. I didn't have a load on the output and the signal was rather noisy, though. It was probably that noisy because of misalignment between the motor and magnet axes.

I found it more interesting, though, that as I moved the motor + magnets away from the brushes, the signal remained (with reduced amplitude). The output amplitude displayed dependency on the angle between the axis of the motor + magnets, and that of the brushes.

While K. Meyl and a few others seem to suggest that the Faraday unipolar generator in such a configuration would not produce changes in the magnetic flux, I would guess that it still might. I think that in a permanent magnet, not all the magnetic domains are perfectly aligned, and that one could consider each domain as an individual magnet with its own edge / rim effects. The magnetic domains at a distance from the spin axis, however, would indeed have translatory motion and could potentially cause a change in the magnetic flux. But then again, the change would probably not be very large, and would average out.

Disregarding magnetic flux, there's also Lorentz force on electrons which would be on translational motion due to the magnet spinning. How this would be interpreted from the perspective of Meyl's vortex physics, I don't know. Would need to play more with vortex physics.

An interesting experiment, also showing a difference between the magnetic field at the middle vs. around the rim of a magnet:

The same dude also experimented with a gyroscope:

By the "Tesla motor," he probably meant the classical Faraday unipolar generator in which a copper disk is spinning in a static magnetic field (clicky).
