1. The problem statement, all variables and given/known data The expression for fall in temperature during adiabatic demagnetization is given by, dT = [(CV)/(C(B)T)][(B(i)^2 - B(f)^2)/2] where C = Curie constant, C(B) = Specific heat per unit volume at constant field, T = Temperature, B(i) and B(f) are the initial and final values of magnetic field. What does V represent in the above expression? 2. Relevant equations 3. The attempt at a solution Is it the volume of the magnetic material?
