Question

working of motor in short

Answer 1

Electric motor: A motor is a device which converts electrical energy into mechanical energy.
Principle of motor : A motor works 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 which rotates it continuously.

Answer 2

an electric motor is a rotating device used for converting electric energy to mechanical energy.
working: the coil ABCD is horizontal when the key is on then the arm AB experiences a force downwards and CD experiences a force in upward direction.
then here the coil rotates anti clockwise.while rotating it reaches vertical n then due to reverse in current flow the arm continues to move again.
so, the force on right side I s always UPWARDS n the force on left side is always DOWNWARDS DIRECTION.
thus the coil rotates anti clock wise.
