I know it’s kind of a stupid question, but I have been thinking this for a while. Do magnets affect the electricity itself that flows inside a wire? For example, say I am charging my phone and it’s connected to a wall socket. If I placed a magnet in the middle of my charger wire (like literally on top of the wire) would the magnet stop the electricity from flowing since it’s getting attracted to the magnet? Would it have any effect at all on the flow of electrons inside the wire?
