Magnetic reconnection - Wikipedia
Magnetic reconnection is a breakdown of "ideal-magnetohydrodynamics" and so of "Alfvén's theorem" (also called the "frozen-in flux theorem") which applies to large-scale regions of a highly-conducting magnetoplasma, for which the Magnetic Reynolds Number is very large: this makes the convective term in the induction equation dominate in such ...
Magnetic Reconnection in the Space Sciences: Past, Present, and …
2019年12月15日 · Magnetic reconnection converts, often explosively, stored magnetic energy to particle energy in space and in the laboratory. Through processes operating on length scales that are tiny, it facilitates energy conversion over dimensions of, in …
I Reconnection converts magnetic energy into kinetic energy, thermal energy, and particle acceleration energy I Reconnection was proposed to explain fast energy release in
Solving a Plasma Physics Mystery: Magnetic Reconnection
2018年10月3日 · Magnetic reconnection causes storms in space and can damage fusion research devices on earth. Researchers are investigating why and how it happens so fast. This graphic shows the magnetic field surrounding the Earth and how it reacted to energy and plasma from a solar flare caused by magnetic reconnection.
Magnetic reconnection - Nature Physics
2015年7月31日 · Earth's magnetic field, immersed as it is within the expanding magnetized plasma atmosphere of the Sun, frequently connects with and disconnects from the solar wind — sometimes explosively — in a...
Magnetic reconnection: MHD theory and modelling
2022年5月10日 · In this review we focus on the fundamental theory of magnetohydrodynamic reconnection, together with applications to understanding a wide range of dynamic processes in the solar corona, such as flares, jets, coronal mass ejections, the solar wind and coronal heating.
Perspectives on magnetic reconnection | Proceedings of the …
Magnetic reconnection is the topological rearrangement of the magnetic field in a plasma on a time scale faster than allowed by microscopic forms of dissipation. Although this definition makes no reference to magnetic energy release, reconnection was originally conceived as a way to power storms and flares in space plasmas and on the Sun.
Magnetic Reconnection at Planetary Bodies and Astrospheres
2024年1月19日 · Here we frame the latest understanding of reconnection theory by missions such as NASA’s Magnetospheric Multiscale (MMS) mission for use throughout the solar system and beyond. We discuss how reconnection can couple magnetized obstacles to both sub- and super-magnetosonic upstream flows.
Magnetic reconnection driven by electron dynamics - Nature
2018年11月30日 · Magnetic reconnection is the process of releasing energy by magnetized and space plasma. Here the authors report experimental observation of magnetic reconnection in laser-produced...
NASA SVS | Fast Magnetic Reconnection and the Hall Effect
2022年4月28日 · Magnetic reconnection is one of the most complex processes known for converting energy from magnetic fields to particle motion. It takes place in solar flares and regions of planetary (and stellar) magnetospheres. Having been studied since the 1950s, many details of the process are still undergoing study.
