What is the equation for a magnetcaloric system?

  1. Nov 13, 2011 #1
    I'm doing a project in thermodynamics, and one of the things I'm researching is the use of the magnetocaloric effect in steam generators. If metal is inside a spining drum, and a permanent magnet is on the outside heating and cooling the metal as it passes by I want to determine how much that metal will heat up and cool and down.

    My assumption is that the energy absorbed by the field will cuase the permanent magnent on the outside to demagnetize. I believe this could be proven if the metal on the drum heats up more then it cools down.
