WebMar 19, 2008 · The phenomenon may also be referred to as a "Bennett pinch"[1] (after Willard Harrison Bennett), "electromagnetic pinch"[2], "magnetic pinch"[3], "pinch effect"or "plasma pinch". Pinches occur naturally in electrical discharges such as lightning bolts, the aurora, current sheets, and solar flares. Birkeland currents are also one of a class of plasma phenomena called a z-pinch, so named because the azimuthal magnetic fields produced by the current pinches the current into a filamentary cable. This can also twist, producing a helical pinch that spirals like a twisted or braided rope, and this most closely … See more 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. … See more Auroral Birkeland currents carry about 100,000 amperes during quiet times and more than 1 million amperes during geomagnetically … See more After Kristian Birkeland first suggested in 1908 that "currents there [in the aurora] are imagined as having come into existence mainly as a secondary effect of the electric corpuscles from the sun drawn in out of space," the story appears to have become mired in … See more Books • Egeland, Alv, Burke, William J.,(2005), Kristian Birkeland, The First Space Scientist , Springer pp. 221, ISBN 1-4020-3293-5 • Peratt, Anthony (1992), Physics of the Plasma Universe, Birkeland Currents in Cosmic Plasma … 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.
