Question

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

Answer 1

Experiment:

1. Take two magnets A and B.
2. Suspend magnet A with a silk thread from support, it will come to rest in north-south direction.
3. Bring the north pole of magnet B close to the north pole of magnet A.
4. We will observe that magnet A moves away from magnet B. This shows that the like poles repel each other.
5. Now, bring the south pole of magnet B near the north pole of magnet A.
6. We can observe that magnet A moves towards magnet B. This shows that the unlike poles attract each other.
