Description

Magnetic resistances (analogous to electrical resistors) are used to model frequency-depending losses in the magnetic circuit. They can be connected in series or in parallel to a permeance, depending on the nature of the specific loss. The energy relationship is maintained as the power

\[P_\mathrm{loss} = \mathcal{F}\,\dot{\Phi} = \mathcal{F}^2 / R_\mathrm{m}\]

converted into heat in a magnetic resistance corresponds to the power lost in the electrical circuit.

Parameters

Resistance: Effective magnetic resistance \(R_\mathrm{m}\), in (\(\mathrm{A}\cdot(\mathrm{Wb}/\mathrm{s})^{-1}\)).

Probe Signals

MMF: The magneto-motive force measured from the marked to the unmarked terminal, in ampere-turns (\(\mathrm{A}\)).
