Active Region NOAA 9661 consisting of various magnetic features (alpha spot, delta spot, pores, and plages) was observed simultaneously in three spectral lines (FeI 630.25, 630.15, and MgI 517.27) using full Stokes spectro-polarimetry with Advanced Stokes Polarimeter at NSO/SP. The formation heights of the three spectral lines span from photosphere to the low chromosphere. The magnetic field vectors are inverted from Stokes parameters using advanced inversion codes. In particular, HeLIx code is used to invert MgI's observation because it is dedicated for chromospheric Stokes inversion. The inverted magnetic field vectors in multiple atmospheric layers enable us to derive the three dimensional structure of the magnetic fields, electric current densities, current helicities, and their height gradients.
