Of course, there's also electromagnetism...
I didn't specify the source of the magnetic field. :-)
No you didn't.
I would think it possible for portable wiring plugged into a cigarette
lighter to be a possible source of magnetism capable of affecting a
compass. I suppose, if both wires are parallel and adjacent, their
fields would cancel, but I wouldn't stake my life on it.
