Why would all magnets cease to work if the Earth's magnetic field went funky? Surely neither the magnets on my fridge nor the magnets in a train's electric traction motors do not depend on the earth's magnetic field being oriented any particular direction. I'm not sure, but I think AC train traction motors don't even have permanent magnets in them. Compasses would get messed up though.
