We study dynamical collapse of isothermal magnetized clouds with two-dimensional axisymmetric numerical simulations. As a model of the cloud, we consider an innnitely long lamentary cloud with longitudinal magnetic eld. An initial model is constructed by adding an axisymmetric perturbation on an equilibrium model. Because of gravitational instability, it… (More)
