State the principle of an electric generator. Write any two difference

1.	State the principle of an electric generator. Write any two differences between electric motors and electric generators.
Answer» Solution :An ELECTRIC generator WORKS on the principle of electronromagnetic induction when a closed coil is rotated in a uniform MAGNETIC field with its axis perpendicular to the direction of the field. The magnetic field lines passing through the coil changes and induce POTENTIAL differences. Hence a cirrent is SET up in it. Electric motor * It converts electrical energy into mechanical energy * It works on the principle of magnetic field of electric current. Electric generator * It converts mechanical energy into electrical energy * It works on the principle of electromagnetic induction.
