2. 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.

3. Solar-Terrestrial Observer for the Response of the Magnetosphere

   en.wikipedia.org/wiki/Solar-Terrestrial_Observer...

   STORM comprehensively fills gaps in our current understanding of the solar wind-magnetosphere interaction by addressing the following science objectives: (A) energy transfer at the dayside magnetopause, (B) energy circulation and transfer through the magnetotail, (C) energy sources and sinks for the ring current, and (D) energy feedback from ...

4. Ionospheric dynamo region - Wikipedia

   en.wikipedia.org/wiki/Ionospheric_dynamo_region

   In the height region between about 85 and 200 km altitude on Earth, the ionospheric plasma is electrically conducting. Atmospheric tidal winds due to differential solar heating or due to gravitational lunar forcing move the ionospheric plasma against the geomagnetic field lines thus generating electric fields and currents just like a dynamo coil moving against magnetic field lines.

5. Electrodynamic tether - Wikipedia

   en.wikipedia.org/wiki/Electrodynamic_tether

   Medium close-up view, captured with a 70 mm camera, shows tethered satellite system deployment.. Electrodynamic tethers (EDTs) are long conducting wires, such as one deployed from a tether satellite, which can operate on electromagnetic principles as generators, by converting their kinetic energy to electrical energy, or as motors, converting electrical energy to kinetic energy.

6. Ring current - Wikipedia

   en.wikipedia.org/wiki/Ring_current

   The ring current system consists of a band, at a distance of 3 to 8 R E, [1] which lies in the equatorial plane and circulates clockwise around the Earth (when viewed from the north). The particles of this region produce a magnetic field in opposition to the Earth's magnetic field and so an Earthly observer would observe a decrease in the ...

7. Magnetic sail - Wikipedia

   en.wikipedia.org/wiki/Magnetic_sail

   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 ...
