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 ... 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 ...

WebJan 8, 2024 · Forced magnetic reconnection, a reconnection event triggered by external perturbation, should be ubiquitous in the solar corona. Energy released during such cases can be much greater than that which was introduced by the perturbation. It is unclear how the properties of the external perturbation and the initial current sheet affect the … 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.
