1. The problem statement, all variables and given/known data A volume of 200cm3 of a paramagnetic substance is maintained at con- stant temperature. The magnetic eld is increased quasi-statically and isothermally from 0 to 10^6 A/m. Assume the Curie law to hold and the Curie constant per unit volume to be 1.885K/m3. (a) How much work would have to be done if no material were present? (Ans: 125.7 J) (b) How much work is done to change the total magnetization of the material when the temperature is 300K and when it is 1K? (Ans: 0.8J) (c) How much work is done to change the total magnetization by the generator supplying the current? (Ans: 236.9J) This question seems simple that is just simply substituting the numbers to the equation.. but I could not get to the answer. Can anyone help?
