Why is repulsion the real test for identifying a magnet?

Answer 1

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 2

Dear Student,

◆ Repulsion is the real test for identifying a magnet because -

• Magnetic dipoles have two characteristic properties - unlike poles attract and like poles repel each other.
• Also magnet can attract magnetic substances (like iron, nickel, Co) which are not magnets.
• On the other hand repulsion property is shown by only magnets.
• Hence, repulsion is the real test for identifying a magnet.

Hope this helps you...
