This question already has an answer here:

We know that current is passed through a circuit if there is a potential difference across the two terminals of the conductor. But, in the case of a short circuit, we say that there is no potential difference between the two terminals and a large amount of current is passed through it. This is a violation of Ohm's law. Isn't it wrong to say that there is no potential difference between the terminals?

Poster is not asking about an Ideal Wire. He is really asking about a very poor inductor. – user6972 Nov 24 '13 at 18:38

Of course in practice there is always some resistance (some 0.001-0.0001 Ohms for the wire) + some internal resistance in the battery/power supply (0.001-1 Ohm). And voltage drop across these resistances will be according to Ohm's law.

So there is no violation, if you count all these parasitic resistances.
