The evolution of a rotating magnetized cloud is studied using a numerical method and a quasi-static assumption. The angular momentum loss rate is discussed, including the critical value of the mass-to-flux ratio at which point the cloud begins to collapse dynamically. The difference between the present case and a plane-parallel cloud is examined. 34 refs.
