B Why is the electric field inside a conductor zero?

  1. Jul 19, 2017 #1
    It can be mathematically shown by Gauss's law that it is true but physically how? In case of a symmetrical conductor(Eg Sphere,Cyllinder) there are charges uniformly distributed and field of one charge cancels out the opposite charge's field! But which are not symmetrical, for them what makes the electric field zero?

    Note that the field within a conductor is zero for the electrostatic case. If there were a field within the conductor, the free charges would move until the field was canceled out.
