# Magnetic Susceptibility

The magnetic susceptibility per unit volume of a magnetic solid is given by x = A/(T-theta) where A and theta are constants independent of magnetic field. How much does the entropy per unit volume of this solid change if, at the temperature T, the magnetic field is increased from H = 0 to H = H_o?
