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:
