I've been trying to get my head around the generation of magnetic fields from moving charges. I can see how a moving point charge or even electrons that constitute a current in a wire can generate a magnetic field but when I extend this concept to an idealised current - an infinite uniformly charged rod moving in the direction of its length - I have problems trying to understand how this motion manifests itself as charge movement as there are no point charge movements to detect - the rod is uniformly (smoothly) charged. If no charge movement is detectable - although the rod is moving - how can a magnetic field be generated?
