Repulsion 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:

The best way to test a magnet is by repulsion because a magnetic substance also has attractive properties. Repulsion is the best indicator because anything made of iron, nickel, or cobalt will also be attracted to something else but not repel it. A surefire indicator of magnetism is repulsion rather than attraction.
