Abstract
Meissner Effect is, of course, an essential characteristic of a superconductor besides the zero resistivity since the discovery by Meissner and Ochsenfeld in 1933. They showed by experiment that the magnetic field inside a superconductor is always zero. This implies that we can think of a superconductor as being a perfectly diamagnetic material. It is highly attractive for the technological applications of the type-II (High temperature) superconductors as YBa2Cu3O7, Bi2Sr2Ca2Cu3O10 and HgBa2Ca2Cu3O8. One important property is the levitation force and its MagLev application. MagLev systems have become very important in the transportation and other applications. These applications are ranging from in an energy efficient prototype of a cryogen transfer line to in space energy storage systems. In this study, we compared that the effect of magnetic levitation force BSCCO and YBCO superconductors. The results were showed that the BSCCO superconductor’s family is very poor in case of the levitation force compared with the YBCO superconductors. It may be attributed that the YBCO family superconductors have the high critical current density which occurs in the case of the flux pinning and the high magnetization behavior.
