Superconductivity has the characteristics of zero resistance, where electricity flows without resistance, and perfect diamagnetism, where magnetic fields are repelled. Zero resistance increases the efficiency of power management technologies such as power transmission, high-magnetic field superconducting magnets, and current limiters, etc. These devices are manufactured by winding superconducting wires in the shape of a solenoid. The perfect diamagnetism can be utilized in contactless bearings, high-efficiency energy storage, and magnetic levitation transportation, etc. The superconductors of a bulk form are used in these devices. In addition, high-temperature superconductors, which are type II superconductors, can trap large magnetic fields inside the superconductor. This characteristic can be utilized to manufacture high-magnetic bulk magnets. Superconducting bulk magnets can be used as portable magnets, wastewater purification magnets, and bioanalysis magnets. This review describes the fabrication process and bulk applications of YBCO superconductors suitable for magnetic levitation and superconducting bulk magnets.
