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:

A	Value: Type: Area (m²) Description: Area of cross section penetrated by flux
l	Value: Type: Length (m) Description: Length associated with magnetic potential difference
