Homework Help: Temperature dependancy of the magnetic permeability

  1. Mar 8, 2007 #1
    I just need see how the magnetic permeability of a piece of steel will change with a change in temperature. The reason why I need this is so that I can see what happens to the eddy current penetration depth when the material is being heat treated

    I already know that the electrical conductivity depends on temperature and the equation that relates!! Just need the magnetic permeability relationship with temperature.

    [tex]\delta=\frac{1}{\bra(\pi f \sigma_{T^{'}}\mu\bra)[/tex]
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
