Birkeland Currents, Z-Pinch, Star formation- Donald Scott
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. Global Birkeland Currents See more WebThe Z-pinch is an application of the Lorentz force, in which a current-carrying conductor in a magnetic field experiences a force. One example of the Lorentz force is that, if two parallel wires are carrying current in the same direction, the wires will be pulled toward each other. In a Z-pinch machine the wires are replaced by a plasma, which ... chinese new year 2015 holiday dates hong kong
