Suspend a bar magnet by a thread or other way, as shown in the figure. Take care that no other magnet or magnetic material is in the vicinity of that magnet. Allow the magnet to come to equilibrium. Now take the north pole (N) of another magnet near it. Why did the north pole of the hanging magnet deflect?

Suspend a bar magnet by a thread or other way, as shown in the figure. Take care that no other magnet or magnetic material is in the vicinity of that magnet. Now take the south pole of the magnet held in your hand near the south pole of the hanging magnet at equilibrium. What could you see this time? What conclusion can be reached from this observation?
