A rendering of the magnetic field lines of the magnetosphere of the Earth. In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. [1] [2] It is created by a celestial body with an active interior dynamo.
The magnetosphere is defined by the extent of Earth's magnetic field in space or geospace. It extends above the ionosphere , several tens of thousands of kilometres into space , protecting Earth from the charged particles of the solar wind and cosmic rays that would otherwise strip away the upper atmosphere, including the ozone layer that ...
This diagram uses embedded text that can be easily translated using a text editor. This SVG diagram contains embedded raster graphics . [1] Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size).
A simulation of a charged particle being deflected from the Earth by the magnetosphere. Thus in the "closed" model of the magnetosphere, the magnetopause boundary between the magnetosphere and the solar wind is outlined by field lines. Not much plasma can cross such a stiff boundary. [1]
The interaction between solar wind and geomagnetic field eventually combine to result in the formation of an electrical current layer, which is called the magnetopause. This electric current layer confines the Earth's magnetic field. The region in which the magnetopause is enclosed in is known as the magnetosphere. [7]

Comment Several components such as bow shock, magnetotail or plasma sheet are in fact cut off so that their actual extent is beyond the image. Also the Earth's atmosphere label here doesn't give a sensible information to me, it may be better to place an ordinary scale bar instead. Brandmeister talk 18:16, 20 May 2013 (UTC) Agree.
