Well, if you have seen Ohm's Law in form j=(sigma) E, where sigma is conductivity, try setting it infinite (for an ideal inductor). You will see that for finite j, E=0. Why doesn't j go to infinity? Well, j is proportional to drift velocity. That can't really go to infinity now, can it? There's a theoretical to limit even if you get into...
