Explanation:
An electric generator converts mechanical energy into electrical energy. It is based on the principle of electromagnetic induction. A conductor is made to rotate between two magnets. The magnetic field around a conductor changes which induces emf and current is generated. The amount of emf produced depends on the rate of change of magnetic field.
