The HH 1-2 region in the L1641 molecular cloud was observed in the near-IR J,H, and Ks bands, and imaging polarimetry was performed. Seventy six point-likesources were detected in all three bands. The near-IR polarizations of thesesources seem to be caused mostly by the dichroic extinction. Using acolor-color diagram, reddened sources with little infrared excess were selectedto trace the magnetic field structure of the molecular cloud. The meanpolarization position angle of these sources is about 111 deg, which isinterpreted as the projected direction of the magnetic field in the observedregion of the cloud. The distribution of the polarization angle has adispersion of about 11 deg, which is smaller than what was measured in previousstudies. This small dispersion gives a rough estimate of the strength of themagnetic field to be about 130 microG and suggests that the global magneticfield in this region is quite regular and straight. In contrast, the outflowsdriven by young stellar objects in this region seem to have no preferredorientation. This discrepancy suggests that the magnetic field in the L1641molecular cloud does not dictate the orientation of the protostars forminginside.
