Permanent Magnetic Levitation and Stability
2001Magnetic levitation applications are becoming more prevalent because permanent magnetic materials have improved in recent years, and their intrinsic instability can be conveniently hindered. In this paper the best current magnetic materials, the rare earths and especially the NdFeB alloy, are presented.

Passive Levitation in Alternating Magnetic Fields
SIAM Journal on Applied Mathematics, 2003Summary: We analyze stability of a levitated axisymmetric top carrying a system of permanent magnets in an alternating magnetic field. We show that there are stable configurations where the top is stationary, and the alternating magnetic field stabilizes the equilibrium position.

Stability of magnetic levitation
Journal of Applied Physics, 1978The levitation forces on metal spheres in magnetic fields of axial symmetry are derived theoretically. Criteria for stability of the center of mass are obtained. It is shown for nonmagnetic samples that the desirable coil configurations are those which provide a constant field gradient along the symmetry axis. The formalism is applied to model coils of

Designing and constructing superconducting magnetic levitation (Maglev) trains using bulk superconductors and magnets is an exciting topic that can challenge science students. In a commercially available magnetic levitation train, a superconducting magnet and electromagnet are used to lift the train and move it on the rail.
