Electric motor. This consists of a loop of wire that is free to rotate in a magnetic field (yellow arrows).
The loop is attached to a power source (left), which drives a current (blue arrows) around the wire. The loop is connected to the power source through a commutator, a pair of half rings, which reverses the flow of current when the loop...
