The simplest example for 3D magnetostatics is actually exactly the same
as for 3D electrostatics.

Things get more complicated if you have inductors (with holes), etc.
GetDP can solve all these problems, but you really need to be familiar
with the theory in order to use them--and adapt the formulation to your
particular problem.

The basic magnetic vector potential and magnetic scalar potential
formulations are sketched here:
