This example compares an electric polyphase inductor with an equivalent fundamental wave reluctance circuit. The phase inductance L and the magnetic fundamental wave reluctance R_m are related by:

R_m = m * effectiveTurns^2 / 2 / L

The two currents

• resistor_e.i[1]
• resistor_m.i[1]

show the same waveforms and thus prove the equivalence of the two different modelling approaches.
