Hi This question really matters me and I would like to someone to point me out (rigorously if possible) why and what makes charge move in ideal conductor. All good conductors are modelled as being ideal so that the Maxwell equations inside the conductor needs not to be solved. So as electric field is zero in the conductor and that the tangential component of electric field on the surface needs to be zero why does current really flow? According to Ohm's law J the current density is proportional to the electrif field which is zero this implies that current density is zero and there is no charge movement as far as I know? So what is the flaw im my reasoning? Thanks!
