The magnetic field of Earth is similar to that of a bar magnet. The magnetic poles are not aligned with the rotation (geographic) poles of Earth. The location of the magnetic poles changes with time and even flips with respect to the rotation poles over geologic history. In the current era, the magnetic pole in the northern hemisphere is a south magnetic pole, which is why the north pole of compass needles point in that direction. Image Credit: UC Berkeley
