Outline of Final Research Achievements

Recently the high magnetic fields are useful in many medicine applications such as a culture of man’s bone or cell. So, the techniques for magnetic field concentration are very important, and the novel electromagnets and trapped HTS bulk magnets have been fabricated and used in the cell culture and the magnetic drug delivery system (MDDS). In these applications, not only the strength of magnetic field but also the magnetic control ability including ON/OFF field switching are needed to enlarge the medicinal effects. On the other hand, superconductors have a perfect conduction and diamagnetism properties. High temperature superconducting (HTS) bulks have a strong diamagnetism and pinning force to trap the magnetic flux. So, in this study, a new field control method using the ring shaped HTS bulk with slit configuration was proposed, and we found that the HTS bulk with slit did control the applied magnetic field, and amplified magnetic fields were obtained at slit parts of HTS bulks.
