Explain Faraday's law of induction with the help of activity


  1. Connect the terminals of a coil to sensitive ammeter.
  2. Push a bar magnet towards a coil, with its north pole facing the coil, the needle in the galvanometer deflects.
  3. It shows that current is set up in the coil.
  4. The galvanometer does not deflect if the magnet is at rest.
  5. If the magnet is moved away from the coil the needle in the galvanometer deflects in opposite direction.
  6. 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.
