Model Modelica.Magnetic.QuasiStatic.FluxTubes.Sensors.Transient.FundamentalWavePermabilitySensor
This sensor is used to determined the effective fundamental wave permeability of a saturated lumped circuit reluctance. For this purpose the sensor is placed such way that the magnetic flux and the magnetic potential difference of the investigated reluctance are sensed. The area of cross section and the effective length of the investigated magnetic path have to be provided as parameters.
See example NonLinearInductor.

Model Modelica.Magnetic.QuasiStatic.FluxTubes.Sensors.Transient.Permeability
This model determines the absolute and relative permeability from two real inputs:
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:
