A finite-element study of a Xi-core transverse-flux single-phase plate levitator is described. The potential function used is the magnetic vector potential. The open boundary of the field is taken into account by means of a `ballooningÂ¿ technique. A method of increasing the lateral stability of the Xi-core is described. It is shown that the C-core levitator form which the Xi-core evolved is, in several respects, the superior machine.
