Halbach multipole magnetising fixtures differ from conventional multipole fixtures in that they are designed specifically to produce a Halbach magnetisation distribution in the permanent magnet material or assembly. They are best suited to magnetising isotropic magnets where the direction of magnetisation is defined by the magnetising fixture rather than the anisotropy of the magnet, however they can also be used for quasi-halbach permanent magnet assemblies constructed from un magnetised anisotropic magnet segments.
Halbach fixture multipole designs can be applied to radial, axial or planar magnet fixture designs.
