The pull is so weak a compass takes some time for the needle to steady. Also the needle has to be very free to respond at all. Seems like too weak a force to be the cause. Kirk

The actual cause of this effect was later determined to be the Earth's magnetic field. Because I live around 45 degrees north latitude, the magnet pull on the north magnets pole is mainly downward toward the ground. This additional pull is very strong and simply causes the? north pole of the magnet to tend to rotate downward more than the south pole. This effect would change depending on where you live on the Earth. -- Contentment comes not from having more, but from wanting less. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * All generalizations are false.
