Magnetic reconnection
The fundamental physics of magnetic reconnection in laboratory and space plasmas is reviewed by discussing results from theory, numerical simulations, observations from space satellites, and recent results from laboratory plasma experiments. After a brief review of the well-known early work, representative recent experimental and theoretical works are discussed and the essence of significant mo...
متن کاملThe scaling of forced collisionless reconnection
We present two-fluid simulations of forced magnetic reconnection with finite electron inertia in a collisionless two-dimensional slab geometry. Reconnection in this system is driven by a spatially localized forcing function that is added to the ion momentum equation inside the computational domain. The resulting forced reconnection process is studied as a function of the temporal and spatial st...
متن کاملThree-Dimensional Magnetic Reconnection
The importance of magnetic reconnection as an energy release mechanism in many solar, stellar, magnetospheric and astrophysical phenomena has long been recognised. Reconnection is the only mechanism by which magnetic fields can globally restructure, enabling them to access a lower energy state. Over the past decade, there have been some major advances in our understanding of threedimensional re...
متن کاملA numerical study of forced magnetic reconnection in the viscous Taylor problem
Two-dimensional, nonlinear magnetohydrodynamical simulations are used to investigate the so-called Taylor problem, in which a small amplitude boundary perturbation is suddenly applied to a tearing stable, slab plasma equilibrium—the perturbation being such as to drive magnetic reconnection within the plasma. This type of reconnection, which is not due to an intrinsic plasma instability, is gene...
متن کاملNonlinear Modeling of Forced Magnetic Reconnection in Slab Geometry with NIMROD
The nonlinear, extended-magnetohydrodynamic (MHD) code NIMROD is benchmarked with the theory of time-dependent forced magnetic reconnection (FMR) induced by small resonant fields in slab geometry in the context of visco-resistive MHD modeling. Linear computations agree with time-asymptotic, linear theory of flow screening of externally-applied fields. The inclusion of flow in nonlinear computat...
