Videos: The Simplest Motors

They look so simple that they should not work, yet homopolar motors do. A homopolar motor is a direct current (DC) electric motor which produces constant circular motion due to this fact: an electric current flowing through a wire that is in a magnetic field feels a force pushing it.

Unfortunately you can’t get much useful power out of this type of motor due to poor efficiency inherent in the design, but it’s an interesting demonstration.
