Summary
Provides an explanation on how to set the polarity of a multi-part permanent magnet according to the user's analysis purpose.
Details
As the frequency with which permanent magnets are used in processes or products increases, this article will provide information on how to set physics and polarity for basic permanent magnet simulation.
For the simulation, a shape with four permanent magnets connected inside a pipe containing air was created as shown in the figure below.
Then, set the physics corresponding to each fluid region and solid permanent magnet region as follows.
At this time, the magnetization direction of the permanent magnet can be set in the physics for the permanent magnet. In the magnetization direction properties of the permanent magnet tree, the z direction was set arbitrarily among the x, y, and z directions.
When the magnetization direction is set in this way, the permanent magnet is magnetized from right to left (z direction), resulting in the characteristics of the S pole on the right and the N pole on the left.
According to the analysis results of this simulation, the magnetic field forms a vector heading from the N pole to the S pole.
And the magnetization direction can be set for each of the four permanent magnets. If you look at the contents, you can use it for each region by setting physics condition >> magnetization direction to specific region values in the region tree of each magnet and setting the magnetization direction created in physics values to the desired direction.
The magnetization direction was set in each permanent magnet area as indicated by the arrow in the figure below and the simulation was performed.
As a result, the magnetic field direction as shown in the picture below was created, and the polarity of each magnet changed depending on the magnetization direction set in each magnet region.
