According to National Geographic, the location of the Earth's magnetic north pole is moving eastward from its current location in northern Canada at a rate of approximately 40 miles per year.
The geographic North Pole (90 degrees north latitude) is defined by the Earth's rotation. Magnetic north, however, is created by the movement of our planet's molten iron core. The movement of all that metal essentially turns the entire planet into one big magnet. The north and south poles of the magnet do not precisely align with the geographic poles, plus we know that they do not stand still, and we know further that the poles reverse positions every 300,000 years, give or take. The last magnetic pole reversal took place nearly 800,000 years ago.
