Synthetic magnetic field B built using Eq. (8). The spectral index of the vector potential is β_A = 5 and the size of the cubes is 120 × 120 × 120 pixels, corresponding to 30 pc on each side. Shown are two-dimensional slices through the cubes of the components B_x (top), B_y (middle), and B_z (bottom). The ratio of the fluctuations of the turbulent component B_t to the norm of the uniform component B₀ is y_B =1 in this particular case, with angles χ₀ = γ₀ = 0°.
