Abstract: | ![]() 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. |
