- 摘要：
PROBLEM TO BE SOLVED: To provide a new technology tool which suppresses diffusion of a magnetic flux even in an ultra high magnetic field of 2T or more to keep the magnetic flux long distance, and further which concentrates the magnetic flux to a local portion.
SOLUTION: This magnetic flux centralization device includes at least a magnetic flux generating source and a magnetic flux induction member having an internal space where the magnetic flux generated by the magnetic flux generating source is introduced and induced. The magnetic flux induction member consists of a superconducting material, and has gradually-decreasing portion where a cross-sectional area of the internal space perpendicular to an inducing direction of the magnetic flux gradually decreases as depart from the magnetic flux generating source, and further has a configuration of causing no current going around the magnetic flux. The magnetic flux generated by the magnetic flux generating source is introduced to the magnetic flux induction member, induced in the gradually-decreasing portion, and then locally converged near the minimum portion of the internal space cross-sectional area of the gradually-decreasing portion.
