How does a electric field move through a wire. I mean when I connect a coil made up of say 100 turns on a coil 1ft in diameter, does the electric field (voltage) Move from one end to other?
or does the Field sort of move from both ends and meet in the middle.
The reason for this one is I was thinking maybe that since one is positive and the other is negative, the Negative end would push electrons to move away and toward the positive and the positive end would cause electrons to move towards it since creates a pull on them. So the two fields that cause the electron movement would sort of meet in the middle.
Since the fields move at light-speed, then that means for the first one where the field moves from point a to b, it would take at least 314.1 Nanoseconds (also PI, lol ). Whereas if the field moves from both ends toward the center then it would take half that at 157 Nanoseconds.
Actually when I think about again I think it would be the first. from point a to b because since one end is technically 0 v, it could not cause any pull whatsoever. So I still want to hear from someone, just to make sure this is correct.
Thanks for any help.
And yes I am talking about the Electric Field (voltage) Not the Electrons themselves because the Electric field moves throughout the wire at the speed of light and the electrons move quite a bit slower.
