Abstract
The AV -A formulation is applied to problems where motion is the source of eddy currents. The Lorentz gauge is used to ensure uniqueness of the solution and leads to a two-step computation procedure: A is computed first, followed by V on moving regions only. A stable and accurate solution of A is obtained through implementation of a Petrov-Galerkin method. Numerical results of 2D and 3D problems are included
