check your compass

the Earth's magnetic pole is not the same as the geographic pole, but in recent years, it is moving toward Siberia.

HowStuffWorks:

The Earth has several poles, not just two. It has geographic north and south poles, which are the points that mark the Earth's axis of rotation. It also has magnetic north and south poles, based on the planet's magnetic field. When you use a compass, it points to the magnetic north pole, not the geographic North Pole. The Earth's magnetic poles move. The magnetic North Pole moves in loops of up to 50 miles (80 km) per day. But its actual location, an average of all these loops, is also moving at around 25 miles a year [ref]. In the last 150 years, the pole has wandered a total of about 685 miles (1102 kilometers). The magnetic South Pole moves in a similar fashion.

more at LiveScience on the various magnetic poles, and it notes that the magnetic pole is getting weaker... and this might mean the poles will flip.
