Abstract. The small compact isolated dark clouds also known as Bok globules are believed to be ideal sites of low-mass star formation. Some of these clouds are undergoing gravitational collapse, and the ambient magnetic field plays a key role in collapse dynamics. A study of projected magnetic field geometry of molecular clouds in relation with their other properties, like the structure, kinematics, and alignment of any bipolar outflows that may be present in the cloud, can give us great insight into the role played by the magnetic field in shaping the structure and dynamics of these objects. The background star polarimetry is generally accepted as a useful tool to map the magnetic field geometry at the periphery of the clouds, which is responsible for the alignment of dichroic grains that produce polarization. We observed stars projected on L1014 to measure linear polarization using ARIES Imaging Polarimeter (AIMPOL) mounted on the 104 cm Sampurnanand telescope during the period of November - December, 2010. L1014 was previously thought as a starless dense core. Dense cores are considered to be starless if they do not contain an Infrared Astronomical Satellite (IRAS) point source to a sensitivity of L ∼ 0.1L (d/140)2. But Spitzer observations of L1014 as a part of Spitzer Legacy programme ``From Molecular Cores to Planet Forming Disks'' came as a surprise. L1014 was found to contain an embedded source, L1014.IRS, with a very low luminosity of L ∼ 0.09L. Furthermore, a compact low-mass bipolar molecular outflow was detected and confirmed to be associated with L1014. In this poster we will be presenting our preliminary results of a study conducted to investigate any possible relationship between the cloud magnetic field orientation with other properties of the cloud and that of the embedded low-mass source.
