Determines permeability from flux and magnetic potential difference

Description
This model determines the absolute and relative permeability from two real inputs:
- RMS magnetic potential difference,
- RMS magnetic flux,
In order to calculate the permeabilities, the area of cross section, , and the geometric length, , of the flux path have to be take into account
In case that the magnetic potential difference is close to zero, permeabilities yield:
