Comparison of 3D magnetodynamic formulations in terms of potentials with imposed electric global quantities Available to Purchase

Methods to impose a voltage or a current in massive conductors in dual magnetodynamic potential formulations (A‐φ and T‐KI‐Ω) are presented. In the A‐φ formulation, a supply voltage can be naturally imposed at the terminals of a conductor, but not a supply current. An equation must be added. This is the opposite for the T‐KI‐Ω formulation. In the paper all methods are described and compared on the basis of an example.
