In the northern hemisphere the needle points to north, in the south it points to the south. On or at the (true middle) "equator" it doesnt point north or south.
If you look at a magnet and cut it in half it will always have a point in the middle where north and south poles blend together. And you can slice the magnet any number of times and it will always have a north, south and neutral middle in every piece no matter how big or thin.

Earth has the same properties....its nothing but a magnet.
Are you pulled to the North Pole?
