“Direct current, the type produced by batteries, does not produce EMF”
Maxwell will be shocked to learn this. Pun intended.
EMF is produced by electricity, DC or AC. The “electric field” is related to the voltage, the “magnetic field” is related to current - thus the term “electromagnetic field”, or EMF.
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).
Indeed!
So would the Demons!!
