Two properties of electromagnetic knots
Abstract
We prove two properties of the electromagnetic knots in empty space. First, that any standard radiation fields (i.e. satisfying E · B = 0 ) coincide locally with an electromagnetic knot. Second, that the electric and magnetic helicities of any knot are equal. These results can be used as a basis for a topological model of electromagnetism.
