  2. Plasma sheet - Wikipedia

    en.wikipedia.org/wiki/Plasma_sheet

    Artistic representation of Earth's magnetosphere. The plasma sheet is highlighted in yellow. In the magnetosphere, the plasma sheet is a sheet-like region of denser (0.3-0.5 ions/cm 3 versus 0.01-0.02 in the lobes) [citation needed] hot plasma and lower magnetic field located on the magnetotail and near the equatorial plane, between the magnetosphere's north and south lobes.

  3. Interplanetary magnetic field - Wikipedia

    en.wikipedia.org/wiki/Interplanetary_magnetic_field

    The heliospheric current sheet is a three-dimensional form of a Parker spiral that results from the influence of the Sun's rotating magnetic field on the plasma in the interplanetary medium. [ 1 ]

  4. Plasmasphere - Wikipedia

    en.wikipedia.org/wiki/Plasmasphere

    The plasmasphere, or inner magnetosphere, is a region of the Earth's magnetosphere consisting of low-energy (cool) plasma. It is located above the ionosphere . The outer boundary of the plasmasphere is known as the plasmapause , which is defined by an order of magnitude drop in plasma density.

  5. 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 ...

  6. Birkeland current - Wikipedia

    en.wikipedia.org/wiki/Birkeland_current

    Schematic of the Birkeland or Field-Aligned Currents and the ionospheric current systems they connect to, Pedersen and Hall currents. [1]A Birkeland current (also known as field-aligned current, FAC) is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere.

  7. Earth's magnetic field - Wikipedia

    en.wikipedia.org/wiki/Earth's_magnetic_field

    This current reduces the magnetic field at the Earth's surface. [27] Particles that penetrate the ionosphere and collide with the atoms there give rise to the lights of the aurorae while also emitting X-rays. [28] The varying conditions in the magnetosphere, known as space weather, are largely driven by solar

  8. Magnetosphere particle motion - Wikipedia

    en.wikipedia.org/wiki/Magnetosphere_particle_motion

    Schematic view of the different current systems which shape the Earth's magnetosphere Trapping of plasma , e.g. of the ring current , also follows the structure of field lines. A particle interacting with this B field experiences a Lorentz Force which is responsible for many of the particle motion in the magnetosphere.

  9. Dynamo theory - Wikipedia

    en.wikipedia.org/wiki/Dynamo_theory

    The most functional feature of kinematic dynamo theory is that it can be used to test whether a velocity field is or is not capable of dynamo action. By experimentally applying a certain velocity field to a small magnetic field, one can observe whether the magnetic field tends to grow (or not) in response to the applied flow.
