Question

Why is repulsion considered as a surest test of magnetism?

Answer 1

1. Magnetism is defined as “all magnets either attract or repel other magnets and magnetic materials”.
2. It can be determined that an object is a magnet by the property of repulsion.
3. 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.
4. The only way material can repel is when it is a magnet.

Thus, repulsion is the surest test for magnetism.
