2. Electro Magnetic Induction It is process in which a conductor goes through stationary magnetic field lines which then causes the production of a voltage across the conductor. Voltage made is called induce EMF Current made is called induce current

3. A.C Generator Dynamo Current generator Looks like an electric motor.

4. A.C Generator Power station generators produce alternative current. They use electromagnets, not permanent magnets to make magnetic fields and then they pass the magnetic field through rotating coils.

5. Transformer When two coils are placed next to each other and the current is one coil is switched on and off or changed, a voltage is induced in the side by coil. This is called mutual induction.

6. D.C Motor It changes electrical energy to magnetic to mechanical energy. Its full form is Direct Current.
