Suppose a straight current carrying wire is immersed in a uniform electric field along its axis. For this problem, please don't worry about complete loops or return paths, just consider a segment of straight wire carrying a current. Since external electric fields don't get inside conductors due to charges on the surface, I expect that field doesn't interfere with the current and voltage drop along the wire due to an independent source such as a battery. I'm assuming that's true.
Now consider that the wire moves through a region of space containing a uniform magnetic field at right angles such that there is a force on the wire. The magnetic field permeates the wire. As the wire picks up speed wrt the field, there should be an electric field seen in the reference frame moving with the wire. This electric field is part of the relativistic transformation of the magnetic field. The question I'm asking is if this electric field acts within the wire to oppose the current and thus acts substantially different that the electric field of the first case? Thanks.
