Abstract :
Finite-element formulations using a current vector and a magnetic scalar potential are presented for low-frequency electromagnetic problems involving voltage driven coils. Windings both with and without skin effect are treated. The voltage constraint is directly incorporated into the finite-element equation system. Numerical examples are also presented.
