The torque on a current loop is zero if the angle between the positive normal and the magnetic field is either `theta =0` or `theta = 180^@`. In which of the two orientations, the equilibrium is stable?

Torque acting on a magnet held at angle theta with a magnetic field is maximum, where theta=

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).
