A short bar magnet placed with its axis at `30^@` with a uniform external magnetic field of `0*16T` experiences a torque of magnitude `0*032J`. Estimate the magnetic moment of the magnet. If the bar were free to rotate, which orientations would correspond to its (i) , stable and (ii), unstable equilibrium? What is the potential energy of the magnet in the two case?
