  1. Take two bar magnets A and B.
  2. Suspend one magnet A with a silk thread from a support so that it is free to swing.
  3. The magnet A will come to rest in the north-south direction. The north pole of the magnet A is in north direction and its south pole is in the south direction.
  4. Now hold the other magnet B in your hand and bring its north pole near the north pole of the suspended magnet A without touching the magnet.

We will observe that two poles repel each other.
