Fig. 7.

Example from our MURaM simulations of granular compression leading to magnetic field amplification in an MBP. The black line shows the magnetic field in the vertical direction while the red line indicates the LOS velocity. The panels below show the evolution of the MBP in the intensity images (top) and the evolution of the magnetic field for the corresponding intensity images, for the time period indicated by the blue dashed line. Orange contours in the intensity images show the MBP, as tracked by our algorithm, used to make the evolution plots above. Analysis of the horizontal velocity of the surrounding granules shows that the granules expand and compress the MBP resulting in an amplification of the magnetic field (the first peak in the top plot). The LOS velocity peaks with the peak in magnetic field. The plots of the magnetic field in the region over this period of time show the compression of the magnetic flux within the intergranular lanes.
