The position of the earth's north magnetic pole was discovered in 1829 near the Boothia Peninsula, over 1,000 miles south of the geographic north pole. The north magnetic pole is the focus of the planet's magnetic field and the place indicated by magnetic compasses. Anyone using a magnetic compass for navigation needs to be aware that of magnetic field shift. The north magnetic pole moves approximately nine miles each year.
