Derive an expression for the magnetic susceptibility of a weak solution of permanent dipoles, the magnetic moment of each of which is equal to M, under the assumption that the dipoles are oriented arbitrarily relative to the direction of the weak magnetic field, i.e. when the magnetic dipole energy is MB kBT. What will be the susceptibility if the dipoles are oriented only with or against the field?
