Material Name:

Initial Relative Permeability:

Saturation B Field: Tesla

This tool provides a quick estimation of magnetization data when only the initial permeability and saturation fields
of a material are known. It provides reasonable transition data from the regime where
B = permeability*H
to the regime where
B = Bsaturation + Permeability_of_free_space*H

Disclaimer:
There are no guarantees about how well this estimation will match any given real ferromagnetic material.
However, if the material is operating beyond the linear regime it will generally be better to model with this data than
as a purely linear material. It is advised that the final modeling be done with either manufacturer provided data or
your own measurement of the material magnetization.
