Permanent magnets are assigned by choosing a permanent magnet material for a solid. These materials are defined by the Magnetization Direction and a demagnetization curve. The Magnetization Direction is a vector where the direction is relative to the global world coordinate system. The magnitude of the vector is ignored. The demagnetization curve is defined using comma-delimited lists, one for the magnetic induction (parameter labeled Demagnetization Curve B (T)) and the other for the corresponding magnetic field (parameter labeled Demagnetization Curve H (A/m) ). At a minimum, two points should be specified: for B it should be Br(residual induction or remanence),0 and for H it should be 0,Hc (coercive force). A more detailed curve can be specified by adding points to these lists.
