HI,
Lets say you have a 100 foot long extension cord, and wind it up on a 12" diameter wooden spool, so that there are several layers, and tightly wound up (such as if you where to buy a coiled extension cord 1000' long like sold at Home Depot)
The coil of wire will act like a transformer, and this can heat up.

And, if you put a permanent magnet mounted on a shaft inside of the coil would you not then have a electric motor????
Though I realize it's more complicated then that.
