North Magnetic Pole

The North Magnetic Pole is the point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downwards.

The North Magnetic Pole moves over time due to magnetic changes in the Earth's core. In 2001, it was determined by the Geological Survey of Canada to lie near Ellesmere Island in northern Canada at 81°18′N 110°48′W / 81.3°N 110.8°W / 81.3; -110.8 (Magnetic North Pole 2001). It was situated at 83°06′N 117°48′W / 83.1°N 117.8°W / 83.1; -117.8 (Magnetic North Pole 2005 est) in 2005. In 2009, while still situated within the Canadian Arctic territorial claim at 84°54′N 131°00′W / 84.9°N 131.0°W / 84.9; -131.0 (Magnetic North Pole 2009), it was moving toward Russia at between 34 and 37 miles (55 and 60 km) per year. As of 2012, the pole is projected to have moved beyond the Canadian Arctic territorial claim to 85°54′N 147°00′W / 85.9°N 147.0°W / 85.9; -147.0 (Magnetic North Pole 2012 est).

Its southern hemisphere counterpart is the South Magnetic Pole. Since the Earth's magnetic field is not exactly symmetrical, the North and South Magnetic Poles are not antipodal: i.e., a line drawn from one to the other does not pass through the geometric centre of the Earth.

The Earth's North and South Magnetic Poles are also known as Magnetic Dip Poles, with reference to the vertical "dip" of the magnetic field lines at those points.

Famous quotes containing the words pole, north and/or magnetic:

    The discovery of the North Pole is one of those realities which could not be avoided. It is the wages which human perseverance pays itself when it thinks that something is taking too long. The world needed a discoverer of the North Pole, and in all areas of social activity, merit was less important here than opportunity.
    Karl Kraus (1874–1936)

    The recent attempt to secure a charter from the State of North Dakota for a lottery company, the pending effort to obtain from the State of Louisiana a renewal of the charter of the Louisiana State Lottery, and the establishment of one or more lottery companies at Mexican towns near our border, have served the good purpose of calling public attention to an evil of vast proportions.
    Benjamin Harrison (1833–1901)

    We are in great haste to construct a magnetic telegraph from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate.
    Henry David Thoreau (1817–1862)
