A short bar magnet is placed in an external magnetic field of 700 gauss. When its axis makes an angle of `30^@` with the external magnetic field, it experiences a torque of 0.014Nm. Find the magnetic moment of the magnet and the work done in moving it from the most stable to most unstable position.
