Gal110-13 is an isolated, unusually elongated comet-shape cloud, which is considered as an example of star forming region resulting from cloud-cloud collision. We carried out optical polarimetry of G110-13 to understand the importance of magnetic field in the
formation and subsequent star formation of G110-13. We compare our results with those from various simulations for cloud-cloud collision and ionization induced cloud evolution and discuss the most preferred mechanism with respect to the magnetic field geometry.
