Name the electric device which converts mechanical energy into electrical energy. Draw the labelled diagram and explain the principle involved in this device.
The electric motor is the device that converts electrical energy into mechanical energy.
Explanation
An electric motor uses the magnetic effect of a current. A motor operates on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it, a force acts on the coil that rotates it continuously. When the coil rotates, the shaft attached to it also rotates. In this way, the electrical energy supplied to the motor is converted into mechanical energy of rotation.
