Question

………….. is the sure test of magnetism for a magnet.

Answer 1

1. A substance that shows magnetic character and produces a magnetic field is called a magnet.
2. It has two poles i.e. north and south poles.
3. A magnet can attract nonmagnetic materials like iron, but a magnet cannot repel nonmagnetic material
4. When a magnet is placed closer to the object and if the object repels the magnet this determines that the object is a magnetic material.

Hence, Repulsion is the sure test of magnetism for a magnet.
