As far as I've seen, two-terminal AC power cords connected to mains are always packed together (hot and neutral wire in one cord or next to each other). I'm also no electrical engineer or anything, but I was just wondering this:
What happens if we run the wires from a socket to some arbitrary device but split apart the hot and neutral wire? After splitting, recombining the wires at the devices again. So let's say the cables are split for the length of 1 meter from socket to the device and are individually insulated. Also, let's assume the current is 0.5A, and the voltage is 230V, and the frequency is 50Hz.
Does splitting the hot and neutral wires from each other create magnetic fields that would be problematic for nearby electronics? Would it be a safety hazard?
And lastly, (I wouldn't say it would be handy but just for the sake of the example) would it be legal?
