Electromagnetic Induction

Can a magnet produce electricity? 

Michael Faraday the English scientist was the first person to prove that a magnet can create a current. To test this, he moved a magnet toward and away from a coil of wire connected to galvonometer. He observed that there was a deflection in the glalvanometer indicates that a current is induced in the coil. The current obtained due to the relative motion between the coil and the magnet is called induced current. The phenomenon by which an AFM or current is induced in a conductor due to change in the magnetic field near te conductor is known as electromagnetic induction.

Observe the deflection of the galvanometer needle when

- The magnet is moved in and out of the coil
- Different pole is introduced
- Number of turns of the coil is changed
