Recently, magnetic levitation techniques have been developed for various fi elds such as energy storage flywheels[1] and magnetically levitated vehicles[2]. The magnetic levitation techniques are very useful because of friction free, energy -loss free, etc. Thus, there are many reports about levitation techniques using high critical temperature (Tc) superconducting magnetic bearings (SMBs) [3]-[5]. SMBs are composed of superconducting (SC) bulk and permanent magnet (PM). These SMBs are based on pinning forces between SC bulk and PM. In this paper, new SMBs composed of SC bulk, SC coil and PM are proposed.
