How Earths Magnetic Field affects the compass'
The reason why a compass works is more interesting. It turns out that you can think of the Earth as having a gigantic bar magnet buried inside. In order for the north end of the compass to point toward the North Pole, you have to assume that the buried bar magnet has its south end at the North Pole, as shown in the diagram at the right. If you think of the world this way, then you can see that the normal "opposites attract" rule of magnets would cause the north end of the compass needle to point toward the south end of the buried bar magnet. So the compass points toward the North Pole. But the Magnetic field affects the northern and southern hemisphere by the needle being magnetized and that is why the magnetic field affects the northern and southern hemisphere on a compass.
