In this study, an experiment to measure the velocity of the superconductive body was performed, which runs without contact on the rail consisting of an array of neodymium or ferrite magnets. On such magnetic rails having several different gradients, the sliding velocity of the superconductive body was measured. From results, the relation between the friction and the velocity of superconductor were discussed. The brief summary of physics for superconductivity, in particular for magnetic properties, was also given. departmental bulletin paper 明星大学 2016-03-24 application/pdf 明星大学理工学部研究紀要 52 5 12 Research bulletin of Meisei University School of Science and Engineering 13467239 https://meisei.repo.nii.ac.jp/record/1256/files/riNo52a03.pdf https://meisei.repo.nii.ac.jp/records/1256 jpn
