Polyphase inductance

Information
This example compares a quasi static electric polyphase inductor with an equivalent quasi static 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 real parts
resistor_e.i[1].reresistor_m.i[1].re
and the imaginary parts
resistor_e.i[1].imresistor_m.i[1].im
of the two currents show the same result and thus prove the equivalence of the two different modelling approaches.
