The Twist of the Birkeland Current Universe of Particles
A Birkeland current (also known as field-aligned current) is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere. In the Earth's magnetosphere, the currents are driven by the solar wind and … See more Auroral Birkeland currents carry about 100,000 amperes during quiet times and more than 1 million amperes during geomagnetically disturbed times. Birkeland had estimated currents "at heights of several … See more Auroral Birkeland currents are constrained along the geomagnetic field. Therefore, the current’s distribution in 3-dimensional space could be largely described using the 2-dimensional distribution of the current’s footprints at a given altitude in the ionosphere, e.g., … See more • Electromagnetism • Magnetohydrodynamics • Bursty bulk flows another name for similar phenomena (discontinuous sudden flows as in Aurorae) See more • Plasma fibres and Walls • Electric Currents and Transmission Lines in Space • Johns Hopkins University/Applied Physics Lab.

WebWhat are Birkeland currents? How are Birkeland currents formed? What do Birkeland filaments have to do with space plasma? Why does astronomy and science refer to these twisting spiralling charged plasma … WebKristian Birkeland determined that large-scale ionospheric currents were associated with the aurora. He deduced this from his surface magnetic field measurements in the polar regions at the beginning of the twentieth century. He suggested that these “auroral currents” originated far from the Earth and that they flowed into and away from the ...
