A model vehicle is constructed which runs without contact to its magnetic rail using oxide superconductors. This paper describes the forces acting between the superconductor and the rail for such a purpose. The attractive and repulsive forces were measured at 77 K as a function of distance between the superconducting pellet and the magnetic rail. As suprconducting pellets, three kinds of materials, i.e., MPMG‐Y123, BiPb2223, and Hg1223, were investigated for three kinds of permanent magnets, i.e., Nd‐Fe‐B, Sm‐Co and ferrite.
