Compass and magnet. The compass has a free-swinging magnetic needle (green) pointing to a dial. The needle will normally align itself with the local lines of magnetic force to indicate the direction of the Earth's north and south magnetic poles. However,a nearby magnet provides a stronger local magnetic influence than that of the Earth,and the needle lines up with the magnet's field,the north of the needle being repelled by the north pole of the magnet | |
