Magnetic fields pervade the interstellar medium are important in the star formation process. Filamentary molecular clouds are known to be the nurseries of star formation. Therefore, determining the morphology of magnetic fields associated with filamentary molecular clouds will enable us to better understand the role of magnetic fields in star formation. Studies and observations by Tahani et al. 2018 and 2019 showed that a bow-shaped magnetic field morphology can explain the magnetic field observations in the Orion-A molecular cloud. We use MagnetoHydroDynamic simulation code of FLASH to simulate a cylindrical filament to study the co-evolution of the filament and magnetic fields to investigate formation of magnetic field wrapping around it.
