Description

pict

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

Ploss = F P = F ∕Rm

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