Abstract

Extended legions of polarized near-infrared light can be produced either by scattering by particles or by transmission through a medium of aligned paramagnetic grains. In principle, if the latter process dominates, polarization studies of extended sources can be used to probe magnetic field structure. Here, we present preliminary results from a polarimetric line study of the bipolar HII region S106.
