Magnetic field taken from MHD simulations: panel a: line-of-sight magnetic field (in kG) with original resolution (5.5 km, please note, that the plots does not reflect the full resolution), panel b: line-of-sight magnetic field (in kG) measured using Zeeman splitting in Fe I 6301 Å line with reduced spatial resolution (110 km), panel c: magnetic filling factor corresponding to the spatial resolution of 110 km. The magnetic filling factor is shown only for |B_obs| field values greater than 100 G.
