modelPermeability
Determines permeability from flux and magnetic potential difference
Information
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:
