Abstract
A magnet apparatus for generating a high gradient and/or high strength magnetic field, comprises: two permanent magnets () located 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 magnets exceeds the magnetic induction of the material of the magnets; and a mask () or masks () on a first end of each of the adjacent permanent magnets (), the mask(s)comprising a non-retentive material covering adjacent end surfaces of the two permanent magnets () with a gap () along a joining line between the two permanent magnets () to form a zone of high-gradient magnetic field above the joining line; wherein the mask(s) () are embedded within the magnets () and/or have a varying thickness and wherein the mask(s) () each have a maximum thickness greater than a tenth of the thickness of the respective magnet ().
