Dec 28, 2015 · If the wire is separated from the circuit and is bend so that it forms a close loop, it will not confuct current. The charges move there almost instantaneously and rearrange themselves to cancel out the electric field. But when the wire is put in a circuit, the the cancellation of field can just never be completed.

Outside of the wire, a radial electric field could be provided by either the divergence-free field induced by the EM waves that give rise to the azimuthal magnetic field, or by the surface charges discussed in Jackson's (1996) and Assis's (1997) papers on …

Sep 7, 2013 · It comes from the fact that many textbooks do not discuss the electric field around the current conducting wire. There is a detailed treatment of a current conducting coax cable in A. Sommerfeld, Lectures on Theoretical Physics, Vol. III (Electrodynamics), Academic Press (1952)

Outside a current carrying conductor, there is, in fact, an electric field. This is discussed for example, in "Surface charges on circuit wires and resistors play three roles" by J. D. Jackson, in American Journal of Physics – July 1996 – Volume 64, Issue 7, pp. 855.

Jan 3, 2015 · Secondly, the forces on the charges in the wire (induced by the electric field) cause an internal polarization - the positive and negative charges will separate just far enough so that the field they generate internally exactly cancels out the parallel component of the external field at each point of the wire. So where the external field ...

Dec 28, 2015 · Actually the electric field inside the wire isn't the same, at least initially. This is what the skin effect is all about. When you first apply a potential to a wire, the electric field is a thin shell only on the outside of the wire. This causes current to flow in a thin layer along the outer surface of the wire.

Nov 25, 2021 · The REAL answer is due to surface chargew being induced when there's an electric field inside wire , these induced surface charges then move to make the field equal. hard to explain in the comments so search it up . obviously in the presence of no surface charges then E field is OBVIOUSLY a function of distance. $\endgroup$ –

May 4, 2011 · In a wire the charges do not accumulate---necessary for setting up an electric field.The charges keep moving--drifting--to set up a current and not a field of their own. If you read good books such as Resnick-Halliday it will say that field inside is …

Mar 4, 2007 · It is falsely believed that the source of the Electric Field within a wire carrying a constant current is the charges that are accumulated in the terminals of a battery. If that was true, the internal Electric Field could not adjust to any change in the geometry of the wire, which is a remarkable attribute.
