Why does aurora usually happen near the poles in the night sky?

The Aurora Boreas only occurs in the northern night sky, or over the North Pole. That is why another name for the Aurora is the Northern Lights. This phenomena happens because the solar winds, in the outer layer of the earths atmosphere, are picking up an electrical charge. This is much like static on a grand scale. In some ways the phenomena is like lightning, in the outer atmosphere. The electrical charge, makes the Northern Sky appear to glow or luminese, in the distance. This only happens in the Northern Sky, because of the earths magnetic qualities.
