The Magnetic Current node specifies a magnetic line current along one or more edges. For a single
Magnetic Current source, the electric field is orthogonal to both the line and the distance vector from the line to the field point. For 2D and 2D axisymmetric models the
Magnetic Current node is applied to
Points, representing magnetic currents directed out of the model plane. For 3D models, the
Magnetic Current is applied to
Edges.
