  • Abstract
    The authors present a model for calculating the levitation force, magnetic stiffness and damping for a superconductor in the presence of the magnetic field of a permanent magnet. Bulk and thin film shapes are chosen for the superconductor. They compare the results for both and conclude that, in general, the thin film shape enhances the magnitude of the force while maintaining a good stability and without increasing the losses associated with small displacements.
