Current sheet forming in the turbulent jet region for the case η = 10⁻³ at t = 300. The right panel shows the ratio between the electric and magnetic components of the electromagnetic energy. The four left panels show zoomed-in portions of the jet domain (see the rectangles in the right plot), where the poloidal magnetic field (color) and magnetic field lines (white lines) are plotted in order to highlight the reversal of the magnetic field and the formation of magnetic islands due to magnetic reconnection.
