Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave. The strengths of the electric and magnetic parts of the wave are related by EB=c, which implies that the magnetic field B is very weak relative to the electric field E.
