*PERMANENT MAGNETIZATION

Specify permanent magnetization.

This option is used to define permanent magnetization through coercivity of a permanent magnet for electromagnetic elements in a transient electromagnetic or magnetostatic analysis. This option can be used only in conjunction with the MAGNETIC PERMEABILITY option and, optionally, with the NONLINEAR BH option.

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variables included in the definition of coercivity of a permanent magnet. If this parameter is omitted, the coercivity is assumed not to depend on any field variables but may still depend on temperature.

Data lines to define the coercivity vector

First line

  1. Global X-component of the direction of the coercivity vector.

  2. Global Y-component of the direction of the coercivity vector.

  3. Global Z-component of the direction of the coercivity vector.

Second line

  1. Magnitude of coercivity. (Units of CL−1T−1)

  2. Temperature.

  3. First field variable.

  4. Second field variable.

  5. Etc., up to six field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six)

  1. Seventh field variable.

  2. Etc., up to eight field variables per line.

Do not repeat the first data line. Repeat the second and subsequent data lines as often as necessary to define the magnitude of coercivity as a function of temperature and field variables.
