1) If I vary charge densities, but keep current density constant, do I get any sort of electromagnetic wave?
2) If the answer to question 1 is no, then if I vary charge densities, but keep current density constant, could I conceivably have a two isolated "open circuit" current elements of finite length, one consisting of charge flowing from point A to point B, and another consisting of charge flowing from point Y to point Z?
3) If the answer to question 2 is yes, then wouldn't there be possible case where the Lorentz force on one of these "open circuit" current elements is not in the exact opposite direction to the Lorentz force on the other "open circuit" current element?
4) If the answer to question 3 is yes, then what bears the difference between these two Lorentz forces so that conservation of momentum is obeyed, if not for the emission of electromagnetic waves (as per answering "no" to question 1)?
