There is no EMF produced by a DC current, or voltage. AC produces EMF. Try sending a radio signal using DC and see how far it gets. AC is used, and digital, to send radio signals(TV,etc), not DC, since DC does not produce an EMF. Also, the way to produce electricity is by running a magnetic field across wires, the field must fluctuate to produce the electricity, and the opposite is true for producing radio waves. Spin it how you will, DC does not produce radio waves(EMF).
“Spin it how you will, DC does not produce radio waves(EMF).”
EMF includes DC to light, my friend - not just radio waves.
Every kid who ever built an “electromagnet” for the science fair can explain it to you. Maybe you should ask one, if you don’t believe me.
