Question

Repulsion is the surest test of magnetism because

• A. attraction occurs between unlike poles
• B. attraction occurs between a magnet and magnetic materials.
• C. Both of the above are true.

Answer 1

The correct option is C

Both of the above are true.

1. Repulsion is the best test for magnetism because a magnet can attract a piece of iron, Cobalt, Nickel, all magnetic material, and like pole of a magnet.
2. In case of repulsion when there are two magnates. The like poles will always repel each other hence it is the best for magnetism.

Hence, the correct option is (C).
