Electronic – Why don’t electrons take the shorter path in coils


Below is a copper coil, presumably forming an electromagnet. From my understanding the electrons travel around the coil to produce a magnetic field. But why don't the electrons jump the wires and take the shortest path?

Below I tried to draw the path that would make sense (for me) for the electrons to take:

This type of wire, used for making coils, is commonly called "magnet wire". https://en.wikipedia.org/wiki/Magnet_wire

It looks like it's bare copper, but it's actually coated with a very thin layer of transparent insulation. Otherwise, you're absolutely right -- if the wire were really bare, the coil wouldn't work because the current could cut straight across from one lead to the other.
