As far as the question of semantics concerning direction of magnetic drift I side with T-Bar.

However once again AA may be harping the more essential issue, that the north magnetic pole is drifting faster than ever, and in a very straight line, which is something unprecedented in the several thousand year map of polar drift that waterbug provided yesterday.

The following video I believe explained why it might be that the magnetic orientation of deep space would reverse when crossing the galactic plain. It has to do with the ultra powerful super massive black hole at the center of the galaxy that is giving the form to the whole galaxy.

I'm still not clear about the details, but that would be the framework of thought.
