I am trying to model the magnetic field of a permanent magnet using PDEModeler. I can only find coefficients for permeability and current density. Does any one know how to specify the magnetic potentional, P, of the magnets? I am trying to model everything using a script and not the GUI. Any help is appriciated.

Are you solving a magnetostatic problem? If so, would it be the value of magnetic vector potential on the boundaries of the magnet?

Thank you Ravi. Yes, it is a magnetostatic problem. I now see where I can enter in the magnetic potential. Do you know what units they are looking for? I am trying to model a Neo35 magnet. I've tried searching online for examples but I haven't been able to find anything.

Good you find your way to setup magnetic potential. PDE Toolbox is unit free. You need to setup the problem by specifying all quantities in consistent units. For example if you stick to SI units for all inputs, you can interpret the output also interms of SI units.
