Located hundred of miles south of the geographic North Pole lies the magnetic North Pole at approximately 82.7° North and 114.4° West (2005), northwest of Canada's Sverdrup Island. However, this location is not fixed and is moving continually, even on a daily basis.
The earth's magnetic pole is the focus of the planet's magnetic field and is the point that traditional magnetic compasses point toward. Compasses are also subject to magnetic declination which is a result of the earth's varied magnetic field. Each year, the magnetic North Pole and the magnetic field shift, requiring those using magnetic compasses for navigation to be keenly aware of the difference between magnetic north and true north. The magnetic pole was first determined in 1831, hundreds of miles from its present location.
