<div class="">It is the other way around: you solve the electrostatic formulation first to get the source of your magnetodynamic problem.</div>
<div class="">The solution will be a combination of both.</div>

Wounded inductors (bobbins) are usually accounted for with a magnetodynamic formulation, that means resistive and inductive effects accounted for.<o:p class=""></o:p></div>
