Forced magnetic reconnection
WebMagnetic reconnection is a phenomenon that occurs in a wide variety of laboratory and space plasmas: e.g., magnetic fusion experiments,1 the solar corona,2 and the Earth’s magnetotail.3 The reconnection process gives rise to changes in magnetic field-line topology with an accompanying trans-formation of magnetic energy into particle energy ... WebMay 16, 2012 · Finite ρ s is known to speed up the forced magnetic reconnection, where ρ s = T e /(m i ω ci), ω ci is the ion cyclotron frequency, and m i is the ion mass [38–41]. Following [ 38 ], the finite ρ s effect is first studied here by neglecting the equilibrium electron density gradient, the ion parallel velocity and the electron inertia in ...

Web1.1 The Origins of Reconnection Theory Interest in magnetic reconnection has continually grown since it was flrst proposed in the 1940s. The reasons for this growth are varied, but the most important is the realisation that reconnection is necessary for the e–cient re-lease of energy stored in planetary, solar, stellar, and astrophysical ... WebSince the Universe is permeated by magnetic fields (in Nature and the laboratory), magnetic reconnection is a ubiquitous mechanism wherever such phenomena occur, including eruptive stellar/solar flares, magnetospheric storms, …
WebA detailed analytical picture of this reconnection process is presented. By studying a simple model problem, the time evolution of magnetic field islands which are induced by … WebMagnetic reconnection in a given system is conventionally categorized as spontaneous or forced. Spontaneous magnetic reconnection refers to the case in which the reconnection arises by some internal instability of the system or loss of equilibrium, with the most typical example being the tearing mode.
