Question

Describe an experiment to illustrate that like poles repel while unlike poles attract.​

Answer 1

Answer:

Take two bar magnets A and B. suspend one magnet A with a silk thread from support so that it is free to swing. In the north-south direction, the magnet will come to rest. The north pole of the magnet is in the north and the south pole of the magnet is in the south direction.

Now hold the other magnet B in your hand, bring its north pole near the north pole of the suspended magnet A (such that the two magnets do not touch each other) as shown in the figure. It is observed that magnet A moves away from magnet B. thus this shows that the like poles repel each other.
