  We analyze high-resolution spectropolarimetric observations of a flux
emerging region (FER) in order to understand its magnetic and kinematic
structure. Our spectropolarimetric observations in the He I 1083.0 nm spectral
region of a FER are recorded with GRIS at the 1.5 m aperture GREGOR telescope.
A Milne-Eddington based inversion code was employed to extract the photospheric
information of the Si I spectral line, whereas the He I triplet line was
analyzed with the Hazel inversion code, which takes into account the joint
action of the Hanle and the Zeeman effect. The spectropolarimetric analysis of
Si I line displays a complex magnetic structure near the vicinity of FER.
Moreover, we find supersonic downflows of 40 km/sec appears near the footpoints
of loops connecting two pores of opposite polarity, whereas a strong upflows of
22 km/sec appears near the apex of the loops. Furthermore, non-force-free field
extrapolations were performed separately at two layers in order to understand
the magnetic field topology of the FER. We determine, using extrapolations from
the photosphere and the observed chromospheric magnetic field, that the average
formation height of the He triplet line is 2 Mm from the solar surface. The
reconstructed loops using photospheric extrapolations along an arch filament
system have a maximum height of 10.5 Mm from the solar surface with a
foot-points separation of 19 Mm, whereas the loops reconstructed using
chromospheric extrapolations are around 8.4 Mm high from the solar surface with
a foot-point separation of 16 Mm at the chromospheric height. The magnetic
topology in the FER suggests the presence of small-scale loops beneath the
large loops. Under suitable conditions, due to magnetic reconnection, these
loops can trigger various heating events in the vicinity of the FER.
