Suppose you have a ring of charge and they can't move around. and you spin it, of course, we will have current. What about the electric field of the ring, the current indicates that there's electric field going around the ring.But Gauss's law kind of suggest, the electric field is the same as when it is at rest (The enclosed charge is the same). But when it is at rest, the field just points straight out/in.
