地理北极：是指北极点，是指地球自转轴穿过地心与地球表面相交，并指向北极星附近的交点。地磁北极：地球是一个具有磁场强度不均匀变化的球体，19世纪20年代，德国著名数学家高斯(K. F. Gauss)发表了关于地球磁场的理论，将地球视为一个具有均匀磁场强度的球体而用数学推导出的磁极，称为地球的地磁南北极...
Mohammed is correct. “When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the n...
In 1958, the United States nuclear submarine Nautilus was the first vessel to cross the Geographic North Pole. Today, dozens of planes fly over the North Pole using great circle routes between continents.
The Geographic South Pole is defined as the southern point on Earth's surface that crosses the Earth's axis of rotation. This is the South Pole that is located at the site of the Amundsen-Scott South Pole Station. It moves about 33 feet (ten meters) because it is located on a moving ...

The Magnetic North Pole is also known as the North Dip Pole and is currently found on Ellesmere Island in Northern Canada. When a magnetic compass points north it is aligning itself with Earth's magnetic field and points to the Magnetic North Pole, not the Geographic North Pole, which is ...
If you have ever used a compass, you know it points to the north. But did you know it usually doesn't point to the geographic North Pole or to the magnetic North Pole? North on a compass can deviate from true north. ©bigstockphoto.com/Remains ...
地磁北极和地理北极之间的夹角角度成为磁偏角。 The daily map instructs is the geography North Pole, but the compass instructs is earth magnetism North Pole.Between earth magnetism North Pole and the geography North Pole's included angle angle becomes the magnetic declination.[translate]...
North pole B. South pole C. East pole D. West pole Correct Answer A. North pole ExplanationThe reason the north pole of a magnet points toward the geographic north when freely suspended is due to the Earth's magnetic field. The Earth itself acts like a giant magnet with a magnet...
(a) If X is known at all points of the surface, Y can be determined; and (b) if Y is known at all points of the surface and X at all points of one meridian line, or more generally at all points of a line on the surface from the north to the south geographic pole, then X ...
