How to calculate the magnetic Resistance of a coil in the magnetic domain? [closed]

Question

Hello,

is there a way to calculate the magnetic resistance of a coil with a magnetic core without knowing the core losses?

The main losses are: Hysteresis losses and eddy-current losses.

How do I condense them in one singel magnetic resistance in the permeance-capacitance analogy used in the Plecs Magnetic Domain, just using the datasheet of the core material? (see Attachment)

The Paper linked in: https://forum.plexim.com/845/calculate-magnetic-resistance-transformer-simulation-magnetic dosen't help me very much because they don't use a magnetic resistance to simulate the losses.

Thanks.

Hi, one option would be that you make use of the curves in  "relative core loss" and fit a first order term (a resistor in parallel with a inductor).
