Magnetic Material with Parameter-based Hysteresis

 Description This magnetic material uses Everett functions to define the B-H hysteresis curve. This material can be used by the TellinenEverett component in the Magnetic > Shapes > Hysteresis palette; the instance name of material should be copied to the material (mat) parameter of the component, and possibly used in the sigma ($\mathrm{\sigma }$) parameter, if eddy currents are modeled.
