How to make a homopolar motor

submitted by mintbbb

1 decade 3 years 6 months 3 weeks ago

WikiPedia: A homopolar motor has a magnetic field along the axis of rotation and an electric current that at some point is not parallel to the magnetic field. The name homopolar refers to the absence of polarity change.

Homopolar motors necessarily have a single-turn coil, which limits them to very low voltages. This has restricted the practical application of this type of motor.
