Hello, I've been trying to figure out something, looked up for answer but didnt find anything.
Suppose you have an electromagnet or any other type of coil, with non insulated wire. All the phenomenons that happens when current flows through the wire are explained by not so complex physics. But as I understand, all this physics laws and explanations assume that the current flows through the wire (parallel to it). My question is, why does the electricity can be assumed to flow that way and not any other way of shorter path (and lower resistance), taking in that the wires are non insulated and current can flow in any direction.
Thanks, I hope I explained my question well.
