Solution

An electric motor is a device that converts electrical energy into mechanical energy.

Diagram: Electric motor 

  Working of an electric motor: 

 An electric motor works on the principle of magnetic effect of electric current. In an electric motor, a rectangular coil ABCD in placed between two magnets in poles N and S. Now, current is passed through it continuously. When current is passed into the coil, it produces a magnetic field around it. The two magnetic fields interact and cause the coil to rotate. When the coil rotates, the shaft attached to it also rotates. In this way, electrical energy supplied to the motor is converted into mechanical energy.
