The North Pole is by definition the northernmost point on the Earth, lying antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been ...
True south is the direction opposite to the true north. It is important to make the distinction from magnetic north, which points towards an ever changing location close to the True North Pole determined Earth's magnetic field .
Marking the North Pole is challenging, as it’s covered by moving sea ice, but its geographic location, also known as the true North Pole, is fixed. By comparison, the magnetic north pole is the ...
N g is geographic or true north, N m is magnetic north, and δ is magnetic declination. Magnetic declination (also called magnetic variation) is the angle between magnetic north and true north at a particular location on the Earth's surface. The angle can change over time due to polar wandering.
The Earth's Magnetic North Pole is actually considered the "south pole" in terms of a typical magnet, meaning that the north pole of a magnet would be attracted to the Earth's Magnetic North Pole. [2] The north magnetic pole moves over time according to magnetic changes and flux lobe elongation [3] in the Earth's outer core. [4]
Compass needles in the Northern Hemisphere point toward the magnetic North Pole, although the exact location of it changes from time to time as the contours of Earth’s magnetic field also change.
Like the North Magnetic Pole, the North Geomagnetic Pole attracts the north pole of a bar magnet and so is in a physical sense actually a magnetic south pole. It is the center of the 'open' magnetic field lines which connect to the interplanetary magnetic field and provide a direct route for the solar wind to reach the ionosphere.
Formed by the coniferous taiga woods of the Arctic, the Arctic tundra encircles the North Pole. It spans from Alaska to Canada to Russia to Greenland to Iceland. Winters in this area are long and ...
