“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.”
to which atmasphere replied,
"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."
Sorry to report you’re still confused. Current traveling down the wire generates a *magnetic field" - that’s the *induced magnetic field* and has absolutely nothing to do with either an em field or the *electromagnetic wave* that is the audio signal. The induced magnetic field is stationary, obeys the right hand rule, whereas the electromagnetic wave (audio signal) travels at near light speed, as I’ve described.
