Actually, a coil can have an effect on the current flowing in it. Technically, there is a magnetic field around any wire with current(ac or dc) flowing in it. coils are often used in electronic circuits for choke circuits, to impeade the flow of ac currents. So, theoretically, yes. Reality, no. Modern electric cables are designed to reduce or eliminate this type of problem. If you will notice, the wires inside most cable are wrapped in a spiral pattern. Not only does this make the cable more flexable, it reduces or eliminates the magnetic induction problem. Overheating due to insufficient cooling is a much more serious problem. BTW. I am in my 70s, and remember all this type stuff that we used to know. All the newbie kids don't know it, because we solved the problems and fixed it before most were born.
