My apologies. Was out of order.
EMF - electromagnet waves.
Spend too much time texting w 14yr old daughter. Short form is king, and doesn’t always work.
You can see in the movie how an ac signal generates waves in a predictable pattern along the conductor. With the complex waves being generated by an audio signal going through a wire, those waves are going to, in turn, have an impact on the signal passing through the wire. That “feedback loop”, is going to change the signal. Not measurable I suspect because we are not yet measuring the right parts of the signal.
