Question

To test whether a given rod is magnet or not, we use

• A. Attractive property of magnet
• B. Directive property of magnet
• C. Repulsive property of magnet
• D. All of the above

Answer 1

The correct option is C

Repulsive property of magnet

Repulsion is the surest test. A permanent magnet causes repulsion when a pole of a magnet is brought near the same pole of another magnet. An unmagnetised magnetic material (like iron, steel, etc) would be attracted to both poles, so we can't use the attractive property of a magnet to test for magnetism.
