  2. Earth's magnetic field - Wikipedia

    en.wikipedia.org/wiki/Earth's_magnetic_field

    The magnetopause, the area where the pressures balance, is the boundary of the magnetosphere. Despite its name, the magnetosphere is asymmetric, with the sunward side being about 10 Earth radii out but with the other side stretching out in a magnetotail that extends beyond 200 Earth radii. [28]

  3. Magnetosphere - Wikipedia

    en.wikipedia.org/wiki/Magnetosphere

    The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...

  4. Magnetosphere particle motion - Wikipedia

    en.wikipedia.org/wiki/Magnetosphere_particle_motion

    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]

    Magnetic north versus ‘true north’ At the top of the world in the middle of the Arctic Ocean lies the geographic North Pole, the point where all the lines of longitude that curve around Earth ...

  6. Dynamo theory - Wikipedia

    en.wikipedia.org/wiki/Dynamo_theory

    If the magnetic field does grow, then the system is either capable of dynamo action or is a dynamo, but if the magnetic field does not grow, then it is simply referred to as “not a dynamo”. An analogous method called the membrane paradigm is a way of looking at black holes that allows for the material near their surfaces to be expressed in ...

  7. Geophysics - Wikipedia

    en.wikipedia.org/wiki/Geophysics

    Fluid motions occur in the magnetosphere, atmosphere, ocean, mantle and core. Even the mantle, though it has an enormous viscosity, flows like a fluid over long time intervals. This flow is reflected in phenomena such as isostasy, post-glacial rebound and mantle plumes. The mantle flow drives plate tectonics and the flow in the Earth's core ...

  8. South Atlantic Anomaly - Wikipedia

    en.wikipedia.org/wiki/South_Atlantic_Anomaly

    The South Atlantic Anomaly (SAA) is an area where Earth's inner Van Allen radiation belt comes closest to Earth's surface, dipping down to an altitude of 200 kilometres (120 mi). This leads to an increased flux of energetic particles in this region and exposes orbiting satellites (including the ISS ) to higher-than-usual levels of ionizing ...

  9. Magnetospheric electric convection field - Wikipedia

    en.wikipedia.org/wiki/Magnetospheric_electric...

    The impact of the solar wind onto the magnetosphere generates an electric field within the inner magnetosphere (r < 10 a; with a the Earth's radius) - the convection field. [1] Its general direction is from dawn to dusk. The co-rotating thermal plasma within the inner magnetosphere drifts orthogonal to that field and to the geomagnetic field B o.
