The filament of a bulb when it gets heated to some threshold level generates the visible light. My query: 1. Why is it called electromagnetic then? Here, if i understand correctly, the waves are produced by the energy emitted by the transition of the electrons between various orbits of the metal filament. So where comes the magnetic field? 2. When light rays propogate then it being an electromagnetic ray, has electric and magnetic fields pulasating perpendicular to each other. Why is it that we feel no effect of the electric field at all? Is it beacuse the field strength is very less? Please correct my logic if there is some flaw in reasoning.
