Line Current (Out-of-Plane) Use the Line Current (Out-of-Plane) node, selected from the Points menu, to specify a line current out of the modeling plane. In axially symmetric geometries this is the rotational (azimuthal) direction; in 2D geometries this is the z-direction. Line Current (Out-of-Plane) Enter a value or expression for the Out-of-plane current I0 (SI unit: A). The default is 0 A.
