1. The problem statement, all variables and given/known data One step in one of the problems in my book (involving calculation of the Poynting vector) asks to find the electric field outside a wire. This wire is resistanceless and the current is steady. 2. Relevant equations Maxwell's. 3. The attempt at a solution Stared at it for a while, had no idea how there would possibly be an electric field, solutions manual says the wire creates a radial one proportional to 1/r.
