Question

Principle of electric motor

Answer 1

Electric Motor

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

 

Principle :

When a rectangular coil carrying current is placed in a magnetic field, a torque acts on the coil which rotates it continuously.

When the coil rotates, the shaft attached to it also rotates and thus it is able to do mechanical work.

Answer 2

Answer:

The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
