Question

Repulsion is the surest test of magnetism. Explain briefly. Who answers first i will mark it as brainliest!!!!!​

Answer 1

pulsion is the surest test of the magnets, because a magnetic substance also has attractive property. Repulsion is the surest test because any substance made of iron,nickel, cobalt will also have attraction but won't have repulsion. Repulsion and not attraction is a sure test of magnetism.

Answer 2

A permanent magnet causes repulsion with one pole when the poles are brought in turn near a suspended magnet. An unmagnetised magnet material would be attracted to both poles. Magnetism can work over a distance and magnets can exert a force (push or pull) on objects without making contact with them.
