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 … WebThis leads to magnetic reconnection between the magnetic cloud and the helmet streamer. Thus, initially magnetic field lines are stripped due to a current sheet at the front of the CME, where magnetic reconnection occurs with the solar wind, and a current sheet at the rear where there is magnetic reconnection with the helmet streamer.
WebApr 3, 2024 · In our simulation study, we use the same numerical setting as in our previous study (Paper I), except for the guide magnetic field, and study the time evolution of reconnection using a two-dimensional PIC simulation.We assume a periodic boundary in the x-direction for x = − 215λ and x = 215λ, and conducting walls for the upper and lower … Webthere is a remarkable development in the theory of the forced magnetic reconnection, Jess et al. (2010)have suggested that there is no observational evidence of explosive …
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 ... Webtivity is directly related to the measured reconnection rate. Following the formation of the plasma, the initial force-free magnetic field configuration@Fig. 1~a!# has an x-point on the midplane of the device. To trigger the so-called ‘‘pull’’ re-connection depicted in Fig. 1~b!, the externally applied po-loidal field is ramped down.

WebDec 18, 2024 · The forced reconnection can happen in a wider range of places, such as in plasma that has even lower resistance to conducting an electric current. However, it can only occur if there is some type of eruption to trigger it. The eruption squeezes the plasma and magnetic fields, causing them to reconnect. イラストレーター 仕事 熊本WebThe two-fluid model of collisionless forced magnetic reconnection is considered where breaking the frozen-in flow constraint for magnetic field lines is provided by electron inertia. pablo menzelWebMagnetic 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. pablo medellinWebThe reconnection rate in MHD simulations is considerably larger than in the earlier study, although still somewhat smaller than in the particle simulations.
