Why? Is it because the poles are aligned with earths, complimenting our own magnetic field?
It appears the magnetic poles are in continuous rotation [1], that sometimes aligns to the rotational poles and sometimes doesn't, with a "flip" event being the binary classification from the slow and smooth traversal over the equator. I feel silly, but I always assumed it was from some more fairly sharp step in the rate of change!
