Abstract
A magnet apparatus for generating a high gradient and/or high strength magnetic field, comprises: two main permanent magnetslocated side-by-side with oppositely oriented magnetic field polarities and end surfaces of opposite polarities next to one another, wherein the magnetic anisotropy of the magnetsexceeds the magnetic induction of the material of the magnets; and at least one maskon a first end of each of the adjacent permanent magnets, the maskscomprising a permanent magnet material covering adjacent end surfaces of the two permanent magnetswith a gapin the masks along a joining line between the two permanent magnetsto form a zone of high-gradient magnetic field above the joining line; wherein the permanent magnet of each maskis oriented with an opposite polarity to the main permanent magnetthat it is attached to.
