Ok I have a general question. Say I have a bunch of electrons moving in a line, not in a wire, but I guess it could be looked at as if it was in a wire. This is my question: So if i picked a point outside of this line of moving electrons, would I find an electric field? I know that there is a magnetic field for sure, and I know that if the electrons were NOT moving, that there would be an electric field. What I'm not sure of is if the magnetic field replaces the electric field or not.
