What is intrinsic magnetic moment ?

A short bar magnet is placed in an external magnetic field of 600 G. When its axis makes an angle of 30° with the external field, it experiences a torque of 0.012 Nm. What is the magnetic moment of the magnet ?

A short bar magnet placed with its axis at 30° with an external field of 800 G experiences a torque of 0.016 Nm. (a) What is the magnetic moment of the magnet ? (b) What is the work done in moving it from its most stable to most unstable position ? (c) The bar magnet is replaced by a solenoid of cross-sectional area 2 xx 10^(-4) m^(2) and 1000 turns, but of the same magnetic moment. Determine the current flowing through the solenoid.

A bar magnet of magnetic moment 1.5 JT^(-1) lies aligned with the direction of a uniform magnetic field of 0.22 T.
