-------------------------------
In Faraday Generator, if the magnet is stationary and the disk rotates
you get an output.
Theory: Charges in moving disk move relative to fixed magnetic field
producing voltage. Connecting wires do not move with respect to magnet
so no induction there. You see a voltage output.



If Magnet is ATTACHED to disk and both spun (Classic "N" machine). Get
output!
Theory: If magnetic field is assumed to not rotate with magnet then we
have in essence the same situation as above.

Theory II: If the magnetic field is assume to rotate with magnet
(bristle theory) then since magnet and disk rotate together there is
no voltage induced in the disk. But magnet field is moving with
respect to hook-up wires and the voltage is induced in THEM!



If Magnet is spun but disk and wires stationary! No voltage.
Theory: If magnetic field does NOT rotate with magnet, then there is
no relative motion with respect to EITHER disk or hook-up wires so
there is no output.

Theory II: If magnetic field DOES rotate with magnet now there is a
voltage induced in the disk and one in the hook-up wires. They are
equal and opposite and CANCEL! Hence no output!

Basically you end up with no definitive answers using these
variations.
