The Surface Magnetic Current Density node adds a boundary condition for a surface magnetic current density
Jms (a flow of magnetic charges along a boundary):
Add a contribution as a Harmonic Perturbation by right-clicking the parent node or click
Harmonic Perturbation in the
Physics toolbar. For more information see
Harmonic Perturbation — Exclusive and Contributing Nodes in the
COMSOL Multiphysics Reference Manual.
Enter values or expressions for the Surface magnetic current density Jms, 0 (SI unit V/m) coordinates. The defaults are 0 V/m.
