Question

Matt has a magnet which is pointing in the North-South direction. He brings a large magnet which is not pointing in the North-South direction close to it. Can you tell what will happen to the first magnet?

• A. It will remain unchanged
• B. It will move such that its direction is parallel to the field line at that point.
• C. It will change its direction to South-North
• D. None of these

Answer 1

The correct option is B

It will move such that its direction is parallel to the field line at that point.

Magnets align themselves in the direction of the magnetic field line due to the strongest magnet around them. Therefore when the large magnet is close to the small one, it will move accordingly so that it becomes parallel to the direction of the field line at that point.
