comment Why do electromagnetic waves oscillate?
Actually, does it necessarily oscillate? I've always thought that as sinusoid waves are solutions to Maxwell equation in vacuum, by Fourier one could construct any kind of wave, including wave packets whose field was a non oscillating "bump". I thought sinusoid waves we always see were just illustrations and they would occur, as a special case, only if the charge was actually oscillating (and not just accelerating, in case of general waves). That would be the answer I'd give to this question. Could you explain me why not?

comment Is Newton's third compatible with retarded Lorentz force?
"If the charges moved uniformly for long enough in the past time, the electric forces are along the joining line of the particles, even if retardation is taken into account" << This sentence alone solves the doubt. I think thats why you found my drawing strange, because its wrong on that point.

comment Is charge 'localization' implicit in the idea of current?
Just a correction (could not edit in time) - I had thought as 'charge spatial discontinuity' or something like that. I thought it wasn't possible to infer flux with a continuous distribution.

comment Is charge 'localization' implicit in the idea of current?
I think I didn't express well in the title because I tried to be short (I'll think on a edit). I think I'd be closer with what I had thought as 'charge concentration in isolated particles' or something like that. I expected that if a flux of 'entities' was detectable, it was by concluding that some of them crossed an imaginary plane, which (I believed) was not possible on the case of arbitrary density. Thus the charge density should be concentrated in small volumes apart from each other for someone to infer a flux. Would you have any suggestion for the question's title?
