Faraday Homopolar Dynamo
Tried out a simple faraday homopolar dynamo or electric generator.
It consists of a disk spinning in a magnetic field. When the disc spins,
an electric current I was produced which was in a direction perpendicular
to the disk's velocity and perpendicular to the magnetic field direction.
A current was produced even if the magnet which is the magnetic field source
spins with the disk. The ammeter measuring the curent I has to have a low
input coil wire resistance like 1ohm = R or less.
