Question

What is the principle of electric motor and generator?

Answer 1

Electric motor: A current carrying loop experiences a force and rotate when place in the magnetic field. The direction is according to flemings left hand rule

Electric generator: It works on principal of electromagnetic induction. When a magnetic field through a coil changes induce current is produce

Answer 2

Answer: (1)principle of electric 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.

(2)principle of electric generator: electric generator works on the principle that when a straight conductor is moved in a magnetic field, the current is induced in the conductor.
