Motors are electronic machines that convert AC or DC electrical current into rotational movement. Most common electrical motors work through the interaction of a magnetic field and winding currents to generate a force.
The basic principle behind electric motors, Ampere's Force Law, was first described by Ampere in 1820 and was first demonstrated by Michael Faraday in 1821. One of the first practical motors was created by Hungarian physicist, Anyos Jedlik in 1828.
Motors are found in many applications around the world from industrial fans to power tools to computer disk drives.
