Abstract :
The authors present a novel method for modeling multiply connected regions based in the A-ψ field representation. The equations are solved in differential form using the finite element approximation. The magnetic vector potential A is used inside conductors, while the magnetic scalar ψ is used to model nonconductors. Holes in eddy current regions are dealt with by adding one extra degree of freedom per hole. The proposed method is more economical (fewer unknowns) than previous solutions and is easily implemented in existing codes based on the A-ψ method
