Certainly it is. It's only possible, however, if there's a changing magnetic field in the loop. Curl(E) = -dB/dt. But in any case, exactly *how* would you arrange to have a current carrying resistive wire carry a current in a closed loop? Where's the EMF coming from? Answer that and you'll see how the field outside the wire plays out. In other words, you have, essentially, hypothesized a closed loop of wire with an E field pointing along the loop all the way around, and then asked how there can be an E field in the *air* going all the way around the loop. Well, how can there be such a field inside the wire to start with? > > Weber's theory predicts a force (distinct from a lorenz force) Could you be a bit more specific here? Last I heard the Lorentz force, F = q(E + vxB), fully explained the behavior of charged particles in E and B fields.
