Technology of passive magnetic levitation using diamagnetic materials at room temperature is very important in various industry fields. Recently, we have designed and manufactured a novel ring Halbach permanent magnet array. And contact-free suspension and rotation of a diamagnetic graphite (PG: pyrolytic graphite) disk was realized on this proto-model ring Halbach PM array. In this paper, we mainly describe the design of both the novel ring permanent magnetic array and the graphite disk, and we shall report preliminary experimental result about a novel contact-free disk suspension.
