I would tend to agree with Greg and Ed on this one due to my recent
experiments. When real current is flowing, (electrodynamically), the
magnetic effect is the thing, and the radial electric field lines
disappear. The classic radial electic field lines are for static or
undulating surface charges only as in the Eqipotential surfaces example
found in the Yost, wiggle wand- ball-wire-ball-detector system where no
current flows, no mag fields are generated, but potential waves do pass
over the system of conductive wires and dielectrics.
