Ambipolar Electric Field
The polar wind or plasma fountain is a permanent outflow of plasma (physics), plasma from the polar regions of Earth's magnetosphere. Conceptually similar to the solar wind, it is one of several mechanisms for the Atmospheric escape, outflow of ionized particles. Ions accelerated by a polarization electric field known as an ambipolar electric field is believed to be the primary cause of polar wind. Similar processes operate on other planets. History In 1966 Bauer and, separately, Dessler ahd Michel noted that since the Earth's geomagnetic field above the poles forms a long tail away from the Sun out beyond the Moon's orbit, ions should flow from the higher pressure region in the ionosphere out into space. The term "polar wind" was coined in 1968 in a pair of articles by Banks and Holzer and by Ian Axford. Since the process by which the ionospheric plasma flows away from the Earth along magnetic field lines, is similar to the flow of solar plasma away from the Sun's corona (the s ...
