What is an electric motor? State its principle.
✓

Answer

An electric device, in which electric energy is converted into mechanical energy is called electric motor. It is based on the principle that when a coil carrying current is placed in a permanent magnetic field, experiences a force due to interaction of the magnetic field of the magnet and the field of the coil.
