地磁场 Earth's magnetic field

(重定向自Geomagnetic)
地球磁圈对地球而言有屏障太阳风所挟带的带电粒子的作用。地球磁圈在白昼区(向日面)受到带电粒子的力影响而被挤压,在地球黑夜区(背日面)则向外伸出。(图片未按照比例显示。)
地球磁北极与“真”北极(地理北极)的差异。
西元2000年相对于地理北极的的磁偏角
西元1700年相对于地理北极的磁偏角。

地磁场,即把地球视为一个磁偶极子(magnetic dipole),其中一极位在地理北极附近,另一极位在地理南极附近,此两极所产生的磁场即为地磁场;通过这两个磁极的磁轴与地球的自转轴大约成11.3度的倾斜。地磁场的成因或许可以由发电机原理解释。地磁场在地表强度为0.3高斯到0.6高斯,向太空则伸出数万公里形成地球磁圈(magnetosphere),有防护太阳风的作用。

Earth's magnetic field 地磁场

(重定向自Geomagnetic)
Computer simulation of the Earth's field in a period of normal polarity between reversals.[1] The lines represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and vertical. The dense clusters of lines are within the Earth's core.[2]
Common coordinate systems used for representing the Earth's magnetic field.

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth's interior out into space, where it meets the solar wind, a stream of charged particles emanating from the Sun. Its magnitude at the Earth's surface ranges from 25 to 65 microteslas (0.25 to 0.65 gauss). Roughly speaking it is the field of a magnetic dipole currently tilted at an angle of about 10 degrees with respect to Earth's rotational axis, as if there were a bar magnet placed at that angle at the center of the Earth. The North geomagnetic pole, located near Greenland in the northern hemisphere, is actually the south pole of the Earth's magnetic field, and the South geomagnetic pole is the north pole. Unlike a bar magnet, however, Earth's magnetic field changes over time because it is generated by a geodynamo (in Earth's case, the motion of molten iron alloys in its outer core).
