The Magnetic Insulation node is the default magnetic boundary condition for the Magnetic and Electric Fields interface and sets the tangential components of the magnetic potential to zero at the boundary n × A = 0. Electric boundary conditions can be applied by adding subnodes to the Magnetic Insulation node. The default electric boundary condition, added under each Magnetic Insulation node, is Ground. The Electric Potential, Electric Insulation, Floating Potential, Terminal, or Normal Current Density subnodes are available from the context menu (right-click the parent node) or from the Physics toolbar, Attributes menu.
