A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis so that the conductor is at right angles to a static magnetic field. source/image: DaveHax How to make a Homopolar motor from a battery, magnets and copper wire. Fun science experiment.
