So how the electric field around the moving charges will look like along with magnetic field ? We are not here to do research or homework for you on demand. Yes, there is a radial electric field E outside a single current carrying conductor and a concentric magnetic field H. If the current is DC then these two fields are independent and when current is AC then E and H are dependent on each other and Electromagnetic waves are produced.
