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.
This template should be used to present information on both intrinsic and induced planetary magnetospheres belonging to both Solar System and extrasolar planets. For the parameters see example template on the right.
English: Artist's concept of the Earth's magnetosphere. The rounded, bullet-like shape represents the bow shock as the magnetosphere confronts solar winds. The area represented in gray, between the magnetosphere and the bow shock, is called the magnetosheath, while the magnetopause is the boundary between the magnetosphere and the magnetosheath.
The remaining terms predict that the potential of a dipole source (ℓ=1) drops off as 1/r 2. The magnetic field, being a derivative of the potential, drops off as 1/r 3. Quadrupole terms drop off as 1/r 4, and higher order terms drop off increasingly rapidly with the radius. The radius of the outer core is about half of the radius of the Earth.

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]
