• B. North pole of a magnet kept in touch with South pole of another magnet
• C. North pole of a magnet kept at a small distance from the North pole of another magnet.
• D. A magnet kept in contact with a non-magnetic piece of wood.

Answer 1

Answer: (A), (B), (C)

The correct options are
A

A magnet kept at a small distance from an iron rod

B

North pole of a magnet kept in touch with South pole of another magnet

C

The magnetic force is a non-contact force. It acts on two magnetic objects in both cases, viz. when they are in contact as well as when they are not in contact.
