Question

the net force experienced by a bar magnet placed in a uniform magnetic feild is

Answer 1

The correct answer should be - Zero.

When a bar magnet or magnetic dipole is placed in a uniform magnetic field, it will not experience any force but it is bound to experience a torque. This torque will align the dipole moment of the bar magnet to align along the direction of magnetic field.

However, if a bar magnet is placed in a non-uniform magnetic field, then it will be subjected to a force and torque.
