Why an electromagnet doesn't makes a short circuit?

The wire is coated with insulation (except, of course, at the ends, where the connections are made). So it doesn't matter if the turns touch each other; the current cam't cut corners.
Yep but I'm talking about the fact that the coil is a simple wire. And if we connect a simple wire to the terminals of the battery it should be a short circuit and heat everything :(
