Magnetic configuration for the final equilibrium state for the radial tilted null shown in Fig. 1, showing a) the 3D configuration with field lines above and below the fan in purple and orange, respectively. The fan plane is outlined in dashed black and the spine is represented in green, with projections onto the xz-plane and yz-plane in dashed green lines. In b), the spine (blue) and the section of the fan plane (pink) are plotted in the x = 0 plane.
