Glushkov lnstitute of Cybernetics Academy of Sciences of the Ukrainian SSR Halyna A. Kozoriz and Kondrat Gishchak Institute of Problems of Modeling In Power Engr. Academy of Sciences of the Ukrainian SSR ABSTRACT There are two well known basic concepts for achiev- ing magnetic levitation of vehicles: one is based on elec- tromagnetic attraction (EMA); and the second method is based on electrodynamic repulsion (EDR). In turn, each of these concepts have at least two variations (1-3)l This paper presents a third form of magnetic levita- tion known in the USSR as the Magnetic Potential Well (MPW) developed by Kozoriz (4), and in the West as Laith- waite's Magnetic River (14). The MPW effect is based on a dc circuit and exhibits characteristics whereby: the magnetic at- traction force passes through a null, before the distance be- comes zero, and changes to magnetic repulsion, as a function of interval separating a superconductive (SC) dc electric cir- cuit and a second dc electro and/or permanent magnet, and/or two-wire dc line pair of infinite length. ' In a gravity field, a MPW vehicle exhibits stable static magnetic levitation distances of about one-half meter at zero vehicle velocity, either above or below a guideway, with inher
