AbstractAbstract We present the POL-2 850 μm linear polarization map of the Barnard?1 clump in the Perseus molecular cloud complex from the B-fields In STar-forming Region Observations survey at the James Clerk Maxwell Telescope. We find a trend of decreasing polarization fraction as a function of total intensity, which we link to depolarization effects toward higher-density regions of the cloud. We then use the polarization data at 850 μm to infer the plane-of-sky orientation of the large-scale magnetic field in Barnard?1. This magnetic field runs north–south across most of the cloud, with the exception of B1-c, where it turns more east–west. From the dispersion of polarization angles, we calculate a turbulence correlation length of 5.0?±?2.″5 (1500 au) and a turbulent-to-total magnetic energy ratio of 0.5?±?0.3 inside the cloud. We combine this turbulent-to-total magnetic energy ratio with observations of NH3 molecular lines from the Green Bank Ammonia Survey to estimate the strength of the plane-of-sky component of the magnetic field through the Davis–Chandrasekhar–Fermi method. With a plane-of-sky amplitude of 120?±?60 μG and a criticality criterion λc?=?3.0?±?1.5, we find that Barnard?1 is a supercritical molecular cloud with a magnetic field nearly dominated by its turbulent component.
