Surface Current in Forms

Among the other uses of forms we can use them to visualize boundary conditions. In this animation The one forms above and below the surface represent H fields. By using forms operators the top forms are first subtracted and then aligned to be parallel to eachother. Then the forms are straighted to be perpendicular to the surface. The result is what we can visualize as current flowing between the forms surfaces.
