Homopolar motor was the first electrical motor to be built. Its operation was demonstrated by Michael faraday in 1821 at Royal Institution in London.

Principle of operation 

The homopolar motor is driven by the Lorentz force. A conductor current flowing through it when placed in a magnetic field perpendicular to current conductor feels the force perpendicular to both magnetic field and current. This force provide torque around axis of rotation and conductor starts rotating.
