Evaluation of magnetic field distribution of superconducting bulk magnets with the same pole arrangement
K. Yokoyama, Tetsuo Oka, K. Noto
We study on the construction of superconducting permanent magnets by RE123 bulk materials and the investigation of these industrial applications such as a magnetic separation. The bulk magnets can generate strong magnetic field in comparison with common permanent magnets and iron-cored electromagnets. In order to propagate an industrial application of bulk magnet in the feature, it is necessary to form various shape of magnetic field, as well as its strength is enlarged. In this paper, the strong magnetic field in the radial direction has been constructed by a pair of bulk magnets. Two Gd123 bulk materials are magnetized by the IMRA method and these are arranged face-to-face with the same pole facing each other. When the radial component of magnetic fields, Bx, is measured in the open space between the magnetic poles with a gap of 50 mm, the area of |Bx| > 0.5 T increases to 148% compared with the single pole.
