Simulation results of the magnetic reconnection separatrix region. a, b color contours for E z and local degree of nongyrotropy (D ng). The z-axis is perpendicular to the current sheet, x-axis is along the background magnetic field, and y-axis is in the out-of-plane direction to complete the right-handed orthogonal coordinate system. White thick curve lines represent the separatrix field lines. Black curves are in-plane magnetic field lines (A y contours). B x is positive for z > 0. Hall field E z and D ng are enhances in separatrix layers. c Terms in generalized Ohm’s law at the intercepts of x = 902d e . Red dashed lines denote the ‘SUM’ of \(- \left( {\varvec{V}_{i} \times \varvec{B}} \right)z\), \((\varvec{J} \times \varvec{B}/{\text{ne}})z\), and \(- \left( {\nabla \cdot \varvec{P}_{e} /{\text{ne}}} \right)z\). Black dotted lines plot the D ng. d The three components of the current density
