Question

The sure test of magnetism is:

• A. attraction
• B. repulsion
• C. induction
• D. attraction and repulsion both

Answer 1

The correct option is B repulsion

repulsion is the sure test of magnetism.

This is because , Repulsion takes place only between two likes poles of a magnet whereas attraction takes place between two unlike poles of a magnet and also between a magnet and a magnetic material . So by attraction it cannot be surely identified the substance is a magnet or not . So , repulsion is the sure test of magnetism .
