Calculating the Properties for a Permanent Magnet

Follow this procedure to calculate the properties for a permanent magnet.

  1. Open the View/Edit Material dialog box.

  2. Set View/Edit Material for to Active Project or All Properties to enable the Calculate Properties for drop-down list.
  3. Select Permanent Magnet from the drop-down list to display the Properties for Permanent Magnet dialog box. This dialog box contains the following fields.

    Mu

    Provide a value for relative permeability.

    Hc

    Coercive field force Hc in the units specified. Provide a value and select units from the drop-down list.

    Br/Mp

    Select this to enable the Br and Mp radio buttons.

    Br

    Residual flux density Br, in Tesla.

    If enabled, provide a value and select units from the drop-down list.

    Mp

    Permanent Magnetization Mp, in A/m.

    If enabled, provide a value and select units from the drop-down list.

  4. Click OK to close the dialog box and return to the View/Edit Material dialog box.

The values for Relative Permeability and Magnitude under Magnetic Coercivity become the new default values.
