A circular copper disk of radius 2 mm and depth 0.5 mm is defined. We also define a time harmonic homogeneous magnetic source field which is oriented orthogonally to the circular surface of the disc. In accordance with the source field, the boundary conditions in the z-direction are set to ‘magnetic’. With the cylindrical disc it is possible to activate symmetry conditions which help to reduce mesh size and therefore calculation time. The basic setup is shown in Fig. 3. These discs do not have holes and are flat, de-burred metal discs. The base edge is not buffed and may need finishing, depending on your needs/preferences. The surfaces are smooth and burnished, but unpolished. It is veryeasy to get a shine on them if needed:simply rub with a small quantity of metal polish using a soft cloth.
