Two-dimensional slices in the x–y plane at fixed z from the reference simulation (δB₀/B₀ = 1) at t = 2 l_c/c, showing the normalized magnetic field strength B/B_rms and the normalized magnetic field-line curvature magnitude κ/κ_rms. The bottom panel shows the joint distribution of B/B_rms and κ (measured in units of the inverse coherence length, ﹩{l}_{c}^{-1}﹩), showing that regions of strong curvature tend to coincide with weaker magnetic fields. A power-law slope of −1/2 is provided for reference.
