Coupling physics, H-A formulation

Hello, i am trying to link two physics, applying the H-A formulation. My objective it to induce current in an hts, superconductor, pickup coil, using a copper coil. I wanted to use the H formulation for the hts coil, using COMSOL Magnetic Fields Formulation, mfh, and the rest (air+copper coil) solved with A, using Magnetic Fields Formulation, in a 2D axisymetrical model.
My question is how the linking/coupling of the two physics should be done, so there is continuity in the electromagnetic properties. I'm guessing that is should be done via boundary conditions, but i am a bit lost where, what should be done in each side (mf and mfh), and using what parameters/values.
Thanks
