Example simulating the Hall effect

Hello,
is there an example illustrating the simulation of the Hall effect that I have missed?
The advertisment of the AC/DC module says it's (easily) possible to simulate Hall sensors, but as far as I can tell I would have to specify my own PDE. I am almost a bit embarrassed to ask since the problem should be trivial to solve.
So is there an easy way to simulate the Hall effect?
Thanks,
Kurt

Hi Kurt,
the Hall effect is not that trivial! Comsol support has actually a good example, basically you have to define an antisymmetric conductivity, where the components depend on the magnetic field.
Based on my experience, if you plan to couple the Hall effect with other models, like thermal models, it is more convenient to define your own PDE anyway, it helps convergence.
