Question

A bar magnet is placed in a uniform
magnetic field whose strength is 0.8
T. Suppose the bar magnet orient at
an angle 30o with the external field
experiences a torque of 0.2 N m.
Calculate:
(i) the magnetic moment of the magnet
(ii) the work done by an applied force in
moving it from most stable configuration
to the most unstable configuration and
also compute the work done by the applied
magnetic field in this case.
