That part is actually true.

a) spin disk only, there is voltage from rim to centre
b) spin both disk and magnet simultaneously, in the same direction,
there is voltage from rim to centre.
c) spin magnet only, NO voltage between rim and magnet.

there's an explanation out there somewhere for this apparent impossibility.

The biggest problem with a Faraday disc is that there is a huge current
producer, with a tiny voltage. the commutation is next to impossible.
They've tried running the rim of the disc in mercury, using it as a
liquid brush. Not much luck.

Someone should build a circuit to act as an inverter for the thousand(s)
amps produced..something along the lines of the peak power tracker
battery charger for solar panels.

ahh....here it is...
