What is the principle of an electric motor ?

Answer :

The electric motor works on the principle of Fleming’s Left Hand Rule which states that when a rectangular coil is placed within a magnetic field and current is passed through the coil, a force acts on the coil which rotates it continuously. When the coil rotates, the shaft attached to it also rotates and in this way the electrical energy supplied to the motor is converted into the mechanical energy of rotation.
