Homework Statement
I am doing a project for which I am learning some aspects of electromagnetism by myself, so you can imagine how lost I am. Well, not completely: I was searching for a ferrite with high permeability as a core material. I learned how the octahedral and tetrahedral sites and the unpaired electrons within the ferrite structure contribute to magnetization. So I went ahead and calculated the saturation magnetization of a ferrite that had a high magnetic moment per molecule.
μ: absolute permeability, μ0: permeability of free space, M: magnetization, H: magnetic field strength, B: magnetic flux density
Homework Equations
Now I don't know how to go from this saturation magnetization to absolute permeability. I know:
B = μ H and B = μ0 (H + M)
putting the two together I have:
μ = μ0 + (μ0 M)/H
The Attempt at a Solution
I don't know how to deal with H to solve for μ (I calculated M and μ0 is a constant). I know H is the applied field strength but I just read that generally M is also a complex function of H... so I don't think I can use any H but the H that gives my saturation magnetization, M. Any help on going from M to μ would be appreciated.
