The Magnetic Field from a Permanent Magnet
In magnetostatic problems, where no currents are present, the problem can be solved using a scalar magnetic potential.This model illustrates this technique for a horse shoe-shaped permanent magnet placed near an iron rod.
The force on the rod is calculated by integrating the surface stress tensor over all boundaries of the rod.
