Abstract
This paper compares finite element formulations for modelling eddy cur rent problems with jumps in conductivity, We study schemes which repre sent the eddy current regions using nodal or edge based magnetic vecto r potentials, The use of all additional electric scalar potential, V, in the eddy current regions is discussed. The nodal A scheme is shown to produce misleading results at low frequencies whilst the AV and edg e A schemes are acceptable.
