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?
In: Physics
Induced currents occur when there is relative motion between a conductor and a magnetic field. This means either the conductor can move, or the field can expand and contract across the conductor (as in the constantly changing AC field). Since the current in the wire past the charger transformer is DC (for all intent and purposes, not changing) and the magnet is not moving, there should be no effect. Theoretically speaking, if you were to move your magnet back and forth you could induce a voltage, but it would be incredibly small.
