When an electrical cord from, say, a lamp, is plugged into an AC wall socket, I'm aware that an electric field forms around the entire length of the cord and even before the lamp switch is flipped on.
1) So would the field around the length of the plugged-in lamp cord, prior to the lamp switch being turned on, be considered an electric field or a static electric field?
2) If it's a static electric field, then would the field, prior to the switch being flipped on, be considered DC even though the current to soon flow through the wire is AC?
3) What is specifically creating the field around the cord (whether static-electric or not) up through that point (before flipping the on switch)?
4) And the field around the length of the plugged-in lamp cord, prior to the switch being turned on, would be a near field, correct?
Thanks so much
