The Magnet node is used to model one or multiple magnets, simplifying the definition of the magnetization direction in each magnet. In the
The Rotating Machinery, Magnetic Interface, this feature is called
Nonconducting Magnet.
Select the Direction method to be used for determining the direction of the magnetization in the magnet. Choose between:
This section is only available when Specify north and south boundaries is selected as the
Direction method. The setting makes it possible to automatically set the magnetization direction for multiple magnets following a certain pattern. Choose between
No pattern,
Circular pattern, and
Linear pattern (or domain index based). When
Circular pattern is selected, the magnetization direction for each pattern element is determined by its position in a circle and a pattern repetition angle. Select
Linear pattern (or domain index based) to repeat the definition of the magnetization direction in a selection of magnets that are linearly displaced.
This section is only available when Circular pattern or
Linear pattern (or domain index based) is chosen as the
Pattern type. The different options are
Repeating,
Alternating, and
User defined. When
Repeating is selected, the magnetization direction is the same in each element. Select
Alternating to instead have the magnetization direction reversed for each repeated element in the pattern. If the alternating pattern is applied to an odd number of magnets, the north and south boundaries should be specified for the first magnet in the pattern. The
User defined option is only available for a circular pattern and allows a custom input that determines how much the magnetization direction should change between each element.
This section is only available when User defined is chosen as the
Type of periodicity, when also having
Circular pattern as the
Pattern type. This angle is added to the magnetization direction for each repetition in the pattern.
This section is only available when Circular pattern is chosen as the
Pattern type. It defines the center of the circular pattern.
This section is only available when Circular pattern is chosen as the
Pattern type. This setting is only available in 3D, and defines the axis around which the pattern is created.
This section is only available when User defined is selected as the
Direction method in the
Magnet feature. This input vector is equivalent to the one that can be added when
Magnetization is selected in the
Magnetic Flux Conservation feature.
This section is identical to the one in the Magnetic Flux Conservation node, apart from that only the options
Remanent flux density and
Nonlinear permanent magnet are available here.
