Why do you need two North Poles?

== == Earth happens to have two North poles, but it is not necessary. * The geographic north pole is one of the two places where the axis of rotation meets the surface. All planets and stars have one geographic north pole and one geographic south pole.

* The north magnetic pole is the point where the magnetic field points directly down, and the south magnetic pole is the point where the magnetic field points directly up. Earth happens to have one magnetic north pole and one magnetic south pole at the moment. Mars doesn't have any magnetic poles. Our sun often has dozens of magnetic north and magnetic south poles in or near its sunspots.
