- Connect the terminals of a coil to sensitive ammeter.
- Push a bar magnet towards a coil, with its north pole facing the coil, the needle in the galvanometer deflects.
- It shows that current is set up in the coil.
- The galvanometer does not deflect if the magnet is at rest.
- If the magnet is moved away from the coil the needle in the galvanometer deflects in opposite direction.
- Further this experiment enables us to understand that the relative motion of the magnet and coil set up a current in the coil. It makes no difference whether the magnet is moved towards the coil. This is one form of Faraday’s law.
