Cell volume-weighted distribution of the angle between the magnetic field, B, and the unit vector, ${\widehat{\mathbf{r}}}_{\mathrm{fil}}$, for filament #2, with ${\widehat{\mathbf{r}}}_{\mathrm{fil}}$ indicating the main axis of the filament, pointing outwards from the cluster’s centre. The dashed line indicates the distribution averaged over the snapshots corresponding to the phase where the average radial velocity of the filament is positive, while the solid curved is averaged on the subsequent infalling part (see Fig. 11). The thin curves in the background indicate the successive individual curves for the cold phase, with darker colours associated with later times.
