A strong lift large clearance suspension can be produced using the attraction between superconducting train magnets and iron track sheets. A null flux arrangement of track loops interacting with the same train magnets will yield magnetic lift/drag ratios of several hundred, and can be designed to give whatever degree of inherent stability is desired. As an example, lift forces of two tons per foot of vehicle can be achieved with clearances of six to twelve inches, and inherent restoring forces in any direction can be designed in the range of 0.2 to 1 g per inch. Calculations are made of lift and restoring forces for various track designs taking into account finite edge and permeability effects. Such a system with its high lift, low drag capability would allow the economic high speed transport of freight as well as passengers. Possibilities include transport of bulk materials, piggy-back trucks, and autos with passengers.
