The magnetic properties of a nonlinear magnetic material can be modified by editing the Magnetization Curve BH parameter. This parameter is defined by a comma-separated list describing a set of points on the demagnetization curve, or B-H curve. The following dialog box is used to display and edit the B-H curve. Expressions, including those that involve the use of existing variables, can be used in this dialog.
To access this dialog box, in the Browser select the material's node. In the property grid expand Magnetic Properties (MS2p/MS3p) and then click Click button to edit/view. Next click the "..." button. You can edit individual cells, insert new rows before and after and delete existing rows. The chart on the right displays the corresponding curve.
