Theoretically the magnetic field in molecular clouds is considered to be dynamically important in star formation but observationally it remains unclear as to how efficiently the magnetic field can affect the star formation processes. If the magnetic field indeed plays a significant role, we expect to observe correlations between magnetic fields and gas kinematics. For a sample of protostars, we analyzed motion of gas using molecular-line data obtained with the Submillimeter Array (SMA) and the magnetic field structures using polarimetric data obtained with the James Clerk Maxwell Telescope (JCMT). We statistically investigated the effects of the magnetic fields on gas kinematics.
