WebAn electromagnetic field (also EM field or EMF) is a classical (i.e. non-quantum) field produced by moving electric charges. [1] It is the field described by classical … WebMar 24, 2008 · 2,041. From a more abstract viewpoint, H and B aren't even the same type of geometrical object. H is a [twisted-]1-form in space, which is associated with a line-integral, and B is a 2-form in space, which is associated with a surface-integral. Similarly, E is a 1-form and D is a [twisted-]2-form.
