Sample trajectories for the magnetic field geometry described by Eqs. (3) and (4) with an additional turbulent component δB, which is generated according to the Fourier superposition of Eq. (15). In the upper panel, the magnitude of the turbulent field is (δB/B₀)² = 0.1. In the lower panel, the turbulence strength is varied together with the background magnetic field strength so that (δB/|B|)² = 0.1 = const. also along the z direction.
