Question

The resultant magnetic field at the center of a bar magnet is zero.

• A. True
• B. False

Answer 1

The correct option is A True

The resultant magnetic field at the center of a bar magnet is zero.

If a bar magnet is placed in a uniform magnetic field B, its poles +m and –m experience force mB and mB along and opposite to the direction of magnetic field B; so net force on the bar magnet is zero.
