By default, the Magnetic Potential node adds a boundary condition for the magnetic vector potential:
where A0 is defined in the
Magnetic Potential section. As the equation suggests, the boundary condition only guarantees that the tangential components of
A and
A0 are equal. Their normal components might deviate depending on specific situations. For reduced field formulation where the background field is specified in the interface settings, the node acts the same as the
Magnetic Insulation feature.
Enter a value or expression for the Magnetic vector potential A0 (SI unit: Wb/m) coordinates.
