     A coil of wire is connected to a sensitive galvanometer as shown in the diagram.  What is observed when the magnet is moved towards the coil?  Explain why this occurs. 
  
  Solution
a) As the magnet is moved towards the coil, it is observed that the galvanometre needle deflect towards LEFT.
b) This is observed because current is induced in the coil such that it opposes the change in flux through the coil produced duee to moving magnet. (LENZ\'S Law)
