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.
A model of short-wavelength features of Earth's magnetic field, attributed to lithospheric anomalies [72] Magnetometers detect minute deviations in the Earth's magnetic field caused by iron artifacts , kilns, some types of stone structures, and even ditches and middens in archaeological geophysics .
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 diagram only shows a net flow from the poles to the equator. However mass conservation requires an additional flow from the equator toward the poles. If that flow was along the axis of rotation, that implies the circulation would be completed by a flow from the ones shown towards the axis of rotation, producing the desired effect.
The dipole model of the Earth's magnetic field is a first order approximation of the rather complex true Earth's magnetic field. Due to effects of the interplanetary magnetic field (IMF), and the solar wind , the dipole model is particularly inaccurate at high L-shells (e.g., above L=3), but may be a good approximation for lower L-shells.
Note: In chondrite model (1), the light element in the core is assumed to be Si. Chondrite model (2) is a model of chemical composition of the mantle corresponding to the model of core shown in chondrite model (1). [1] A photograph of Earth taken by the crew of Apollo 17 in 1972. A processed version became widely known as The Blue Marble. [2] [3]
Magnetic sail animation. A magnetic sail is a proposed method of spacecraft propulsion where an onboard magnetic field source interacts with a plasma wind (e.g., the solar wind) to form an artificial magnetosphere (similar to Earth's magnetosphere) that acts as a sail, transferring force from the wind to the spacecraft requiring little to no propellant as detailed for each proposed magnetic ...
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. --Wingtipvorte X PTT ∅ 22:13, 20 May 2013 (UTC) Support I think that if all components were not cut off then the earth would be too small. The diagram is ...
