Variation in the magnetic field components at x = 0 along the y direction at t = 120.22 (left) and 137.39 s (middle). The horizontal dashed black lines mark the zero field components. The vertical dashed black lines are located at y = 27.34 and 26 Mm (at x = 0) for the left and middle panels, respectively. The right panel shows the distribution of the v_x and v_z components along a horizontal axis situated at those values of y at t = 120.22 and 137.39 s, respectively.
