Question

A compass needle is placed near bar magnet. Now, compass needle is placed above on axis of bar magnet. Net magnetic force on compass needle

• A. May be zero
• B. Must be zero
• C. Cannot be zero
• D. None of the above

Answer 1

The correct option is A May be zero

Force will be zero if distance of end of compass needle is symmetric from pole of magnet. But if it is assymetric, then a net force will act on compass needle.
