AbstractThe dynamics of large-scale magnetic loop in three dimensions is studied by MHD simulations. The spontaneous fast reconnection model is used in this study. Once a current-driven anomalous resistivity is ignited in a local region in a current sheet, the fast reconnection mechanism spontaneously evolves. As a result, large magnetic loop is developed, and very localized high pressure region appears outside of the magnetic loop. Near the region between magnetic loop and the high pressure region, very large vortex flow appears, and then, the high pressure region more and more localized due to this vortex. On the other hand, we suggest that the spatial size of initial disturbance to the direction of current is very important to evolve of three dimensional fast reconnection processes.
