The Magnetic Field from a Permanent Magnet
Model ID: 78
As an example of a magnetostatic problem, consider how to model a horseshoe-shaped permanent magnet. One way is to treat the entire magnet as a ferromagnetic material, where the two end sections are defined as being pre-magnetized in different and opposite directions. An alternative is to set surface currents on the pre-magnetized parts. In this tutorial model, both of the alternatives are performed.
