Passive Conductor
The Passive Conductor node allows for modeling conducting metallic objects that are not connected to external circuits. The typical use case is a metal that is neither a magnet, nor a laminated core (like copper, or aluminum). As for the Magnet feature, it supports internal circulating currents constrained by insulating boundary conditions (including interior boundary conditions). It supports soft magnetic materials models comparable to the Laminated Core feature, but without dedicated settings for laminated materials.
Constitutive Relation B-H
This section is identical to the one in the Ampère’s Law node, except for that only the options Relative permeability, B-H curve, and Effective B-H curve are available here.
Constitutive Relation Jc-E
This section is identical to the one in the Magnet node.
