Question

Nikhilesh has a small piece of metal and a thread. He wants to find whether the metal is a magnet or not. What are the things he would need?

• A. A piece of magnetic substance
• B. A magnet or a compass
• C. A piece of non-magnetic substance
• D. He does not require anything more

Answer 1

The correct option is D He does not require anything more

When a magnet eg. bar magnet is suspended freely with a thread. Then it will always bends towards North pole i.e., it deflects towards North pole i.e, it deflects towards North pole. But a simple metal will not show any deflection. So, he will just take that metal piece and suspend it freely with a thread then it will not show any deflection this will give sure test that piece is not a magnet.

So, he does not required anything more.

Hence, option : D.
