Question

A device which converts electrical energy into mechanical energy is called _______.

Answer 1

1. A current-carrying conductor when placed in a magnetic field experiences a torque.
2. The interaction of the magnetic field lines and the electric field lines inside a motor produces a torque which rotates the blades of the motor.
3. Hence, the electric energy provided to the coil of the motor gets ultimately converted into mechanical energy which rotates the blades of the motor.
4. Below is the simplified diagram of a motor.

Hence, a device which converts electrical energy into mechanical energy is called a motor.
