Abstract

A novel method to control a magnetic field distribution in a magnet is devised with use of inter-poles made of anisotropic magnet material. One can generate a gradient field in a constant gapped magnet with this technique; the effective length of the magnet can be constant, independent of the entrance position. Such a magnet can have not only constant gap but also smaller fringing field compared with a conventional one that controls its field distribution by changing the gap height
