Calculating the Properties for a Permanent Magnet
From the View/Edit Materials window:
- Set the Relative Permeability to Simple.
This enables the Calculate Properties for... drop down menu at the bottom of the window.
- Click Permanent Magnet from the drop-down menu.
- Click OK to close the dialog and return to the View/Edit Materials window.
This displays the Properties for Permanent Magnet dialog box. This contains the following fields.
|
Mu (enabled by default) |
Provide a value for relative permeability. |
|
Hc (enabled by default) |
Coercive field force Hc in the units specified. Provide a value and select units from the drop-down menu. |
|
Br/Mp (disabled by default) |
Checking this enables the radio buttons that let you specify either Br or Mp. |
|
Br |
Residual flux density Br, in Tesla. If enabled, provide a value and select units from the drop-down menu. |
|
Mp |
Permanent Magnetization Mp, in A/m. If enabled, provide a value and select units from the drop-down menu. |
The values for Relative Permeability and Magnitude under Magnetic Coercivity are updated as new default values.
