Numerical Investigation on Applicability of <i>j</i><sub>C</sub>-Measurement Method to Multiple High-Temperature Superconducting Tape

A numerical code has been developed in order to investigate the applicability of permanent magnet method vertically-stacked multiple high-temperature superconducting (HTS) tapes. The was proposed simply and contactlessly measure critical current density HTS tape. By this method, is estimated from proportional relation between Lorentz force working on magnet. Maxwell equation, coupled with superconductivity characteristics, solved by edge-based finite element effect number tapes force. As a result, it clear that can be applied measurement although there an upper limit which measured. In addition, using stronger magnet, when more are stacked.
