If `m` is magnetic moment and `B` is the magnetic field, then the torque is given by

Magnetic Moment and Torque

A flat coil carrying a current has a magnetic moment vecmu . It is placed in a magnetic field vecB . The torque on the coil is vec(tau)

A bar magnet of magnetic moment 6 J//T is aligned at 60^(@) with a uniform external magnetic field of 0.44 T. Calculate (a) the work done in turning the magnet to align its magnetic moment (i) normal to the magnetic field, (ii) opposite to the magnetic field, and (b) the torque on the magnet in the final orientation in case (ii).
