“There it was, right in front of me in black and white! The current does not flow around a loop setting up a magnetic field as I had, along with countless other engineers, been taught in high school and university. It is the other way round. The electric current is but an artifact of a more fundamental entity.”You can work that either way you want to- put the em field somehow in place and the current will flow in the wire, or put the current through the wire and the em field will be generated. Either way its a red herring and has nothing to do with directionality nor suggests a means for directionality.
