Magnetic Permeability

Isotropic Magnetic Permeability with Constant Mu Values

You can select the Const Mu model to define a material with constant values for the real magnetic permeability, ${\mu }_R$ .

Input Data	Description
MuR	Real part of the magnetic permeability, ${\mu }_R$ .
Use temperature-dependent data	Specify magnetic permeability values that depend on temperature. A Temperature field appears in the data table.

Orthotropic Magnetic Permeability with Constant Mu Values

When you define orthotropic magnetic permeability, the real magnetic permeability value, ${\mu }_R$ , is a tensor with different permeability values in the X, Y, and Z directions.

Input Data	Description
MuR (X), MuR (Y), and MuR (Z)	Magnetic permeability ( ${\mu }_R$ ) in the X, Y, and Z directions.

Permeability of Soft Magnetic Materials

You can select the soft magnetic model to describe the magnetic behavior of soft magnetic materials. This model lets you specify the dependency of the magnetic flux density, $B$ , on the magnetic field intensity, $H$ .

Input Data	Description
H-Field	Magnetic field intensity, $H$ .
B-field	Magnetic flux density, $B$ .

Permeability of Hard Magnetic Materials

You can select Hard Magnetic model to describe the magnetic behavior of hard magnetic materials. Here you can specify the dependency of the magnetic polarization, $J$ , on the magnetic field intensity, $H$ .

You can model temperature-dependent behavior for the demagnetization curve (or $HJ$ curve) by clicking Temperature and specifying values for the magnetic field intensity and magnetic polarization at a series of temperature points.

Input Data	Description
H-Field	Magnetic field intensity, $H$ .
J-field	Magnetic polarization, $J$ .
