A study of the motion of quantized vortices in cylindrical superconducting thin films was undertaken to determine the feasibility of constructing a magnetic shield in which the trapped transverse magnetic flux could be systematically swept out. The idea is to induce vortex-antivortex annihilation along one side of the cylinder under the influence of the Lorentz force using a transport current parallel to the axis of the cylinder. It is found that for a granular aluminum film approximately 1500 A thick, there is a narrow temperature window near the critical temperature in which the vortices and antivortices can indeed be swept to one side and the internal field significantly reduced.
