Shear Magnetic Field Reconnection near the 3-D Null Point
Abstract
Using a 3-D MHD numerical code the shear magnetic field reconnection near the 3-D null point is studied. To demonstrate the topological changes of magnetic field lines during the shear reconnection two cases: (a) without and (b) with the anomalous resistivity are compared. For simplicity a high beta plasma is assumed. It was found that during this process magnetic field lines on one side of the "fan" structure are reconnected with those on the opposite side of the fan. Thus, the magnetic field lines reconnect places in a very broad range of angles in the plane of the fan layer.
