Question

is a sure test for magnetism.

• A. Induction
• B. Attraction
• C. Repulsion

Answer 1

The correct option is C Repulsion

By virtue of magnetism, all magnets either attract or repel other magnets and magnetic materials. To check whether an object is by itself a magnet, the only surer way is by the property of repulsion. Because when we have a magnet with a known pole and we check for attraction , the attracted object can either be a magnet with the opposite pole or a magnetic material itself. The only way a material can repel is when it is a magnet. Thus, repulsion is the surer test for magnetism.
