Example of the evolution of the three MMFs marked in cyan boxes visible in Fig. 4 (red boxes) for three different times in TFG images superimposed NIRIS magnetic field (in yellow and white). Each row follows a differenet MMF. In each cyan box, there a white small area that indicates the presence of magnetic field or MMF. The arrows indicate the direction of their trajectories as in Fig. 4. The threshold of the magnetic field is 20 Gauss. The panels of this figure are extracted from the online movie (Famb.mp4). The white or yellow lines in the diagonal are artifacts due to field rotation.
