Question

Give a reason for the following;

• Repulsion is the sure test for magnetism.

Answer 1

SURE TEST for Magnetism-

Explanation:

1. Attraction can take place between unlike poles of the magnets and also between the magnet and magnetic material.
2. Attraction cannot surely identify whether the substance is a magnet or not.
3. Repulsion always takes place between the like poles of two magnets.
4. Hence, the sure test for magnetism is the property of repulsion only.
