Levitation Capability of a Bulk YBa₂Cu₃O_7-x with NdFeB Guideway by Two Magnetization Methods

Abstract:

On the requirement of high temperature superconducting (HTS) Maglev transportation application, levitation capability of bulk YBa2Cu3O7-x on the HTS Maglev test vehicle has been investigated experimentally by pulsed field magnetization (PFM) and field cooling (FC). The result showed that YBa2Cu3O7-x sample magnetized by the pulsed magnetic field behaves like a magnet in the other external field, and the magnetization direction of bulk determines its levitation force and lateral force mode (magnitude and direction) over NdFeB permanent magnetic guideway (PMG). On the other hand, static field cooling condition is with an electromagnetic field realized by Field Control Electromagnets Workbench. Two important forces of the same bulk were measured and compared with the PMG when the bulk had the same max trapped field by FC and PFM methods, and the results show the difference effects by these two magnetization methods.
