I think the compass needle is magnetised to the same polarity as the Earth so it should point to Mag North regardless. Interestingly Mag north is not at the North pole so standing on the North Pole it will point South!
The magnetic North Pole is a location in northeastern Canada at which a magnetic compass stands nearly on end. Actually the highest declination of a compass needle was measured at 89 degress 56 minutes. The magnetic North Pole is moving northwestward at about 10 kilometers per year...
