Hello, i am learning to use COMSOL, and i wanted to know how i can excite a superconducting HTS coil with a DC current. I started to learn with a regular copper coil, using Magnetic Fields module, mf, where i can use the coil domain, defining there the turns, and the current excitation. Now i wanted to try with an HTS coil, now represented with an homogeneous bulk of hts tape, with different turns. For this I am using the Magnetic Fields formulation, H formulation, mfh. Using the Farady's Law domain for the hts, where i define the power law for the non linear resistivity. My question is, using this module how can i excite this coil with a current, for a stationary study? And for future frequency domain studies, is it possible to connect to an electrical circuit? Like with the coil domain, from mf?

Thanks, Vitor
