I am trying to model magnetic shielding with mu metal, and from this comsol seminar https://www.comsol.com/video/modeling-electromagnetic-shielding-in-comsol-multiphysics, I am told to use the transition boundary condition to model this.

My question is, why is this a valid way to model magnetic shielding? Looking at the documentation for the transition boundary condition, there is no mention of magnetic fields.

Thanks

I assume you are talking about modeling using the emw mode.

In the emw mode the entire FEM problem is formulated in terms of the electric fields, and magnetic fields (if needed) are calculated from the electric fields. So the transition boundary condition is also necessarily formulated in terms of electric fields (only).
