Abstract :
This paper presents a magneto-dynamic finite element formulation coupled with circuit equations using the time-integrated electric potential. This formulation at high frequency, including displacement currents, permits the study of electric-magnetic interactions in electric coils. The massive conductors in which eddy currents can develop are considered. This formulation can resolve the parasitic capacitive effect problems in massive components for an axi-symmetrical domain
