Consider an infinitely long stationary conductor which carries a steady uniform current.
1. At an arbitrary Test Point outside the conductor the Electric Field should be ZERO according to Maxwell's Equation.
2. But if Special theory of Relativity is considered, the moving charges (electrons) inside the conductor is an inertial frame moving with a fixed velocity with respect to the Test Point. Hence there will be a Lorentz Contraction for the moving frame resulting in the change of (negative) charge density. This will give rise to an imbalance in the +ve and -ve charges in the conductor and hence an Electric Field will be experienced at the Test Point.
How is this discrepancy resolved?? And what does happen in reality??
