WebMuch work has been conducted on Birkeland currents in the past few years with ground-based and satellite observations, theory, and simulations. Significant advances have … WebKristian Birkeland In the early 1900's the Norwegian physicist Kristian Birkeland took expeditions into the Arctic Circle to study the Aurora. He found that magnetometers changed direction when the aurora appeared. This implies that there must be electric currents flowing high in the atmosphere. Birkeland theorized that the solar wind is a current …
Birkeland currents explained
Did you know?
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.
