Question

Which of the following is the surest test of magnetism?

• A. Attraction
• B. Repulsion
• C. Breaking a magnet

Answer 1

The correct option is B

Repulsion

1. Attraction and repulsion are the properties of a magnet.
2. The attraction takes place when we bring a magnetic material near a magnet or when two opposite poles of a magnet are near each other.
3. But repulsion takes place only when the like poles of the magnets are near each other.
4. Thus, repulsion is a sure test of magnetism.

Hence option B is correct.
