Why is repulsion a surer test of magnetism than attraction?

Open in App

Solution

Because repulsion occurs only between two like poles of a magnet, whereas attraction occurs between two unlike poles of a magnet as well as between a magnet and a magnetic substance, so repulsion is a definite test for magnetism.
Magnetic separation is a technique that uses a magnet to separate usable magnetic material like steel and iron from the garbage.
