The establishment of the nondestructive inspection technology with plant structures has been stimulated by the recent occurrence of cracks in the nuclear power plant structures. In this research, a uniform eddy current multi-probe to apply to the ...

AC magnetic properties of bulk high-temperature superconductor were evaluated with three-dimensional finite element method (FEM) analyses. When an external magnetic field strength increased, the heat was generated in weak link parts and the critic...

Since bulk high-Tc, superconductor (HTS) characteristics are not homogeneous in some specimens due to grain boundaries and cracks, magnetic characteristics should be assessed under the static and AC magnetic field. Thus, static magnetic characteri...

As for a general transformer using a ferromagnetic core, the magnetic flux may leak by using the high frequency and the overload. When the magnetic flux leaks from the core, the secondary voltage and its power transfer efficiency decrease. Bulk hi...

Recently, bulk-type high-Tc superconductors (HTSs) having a characteristic of critical current density over 104 A/cm2 in liquid nitrogen (77 K) and at 1 T have been produced. They are promising for many practical applications such as a magnetic be...
