The Magnetic Continuity node does not apply any condition or constraint to the model. Its purpose is to allow the application of electrical boundary conditions by means of the subnodes 
Electric Insulation and 
Contact Impedance. The subnodes are available from the context menu (right-click the parent node) or from the 
Physics toolbar, 
Attributes menu. Use this feature to model thin layer with particular electrical properties but with the same magnetic properties of the surrounding medium.
