    摘要： There are disclosed magnet arrays and methods for generating magnetic fields. In embodiments magnet arrays comprise a plurality of polyhedral magnets arranged in a lattice configuration and at least partly enclosing a testing volume, the magnet array having an associated magnetic field with a designated field direction {circumflex over (v)}, wherein the magnetization direction {circumflex over (m)} of an individual polyhedral magnet located at a displacement vector {right arrow over (r)} from an origin point in the testing volume is determined by the formula: {circumflex over (m)}=(2({circumflex over (v)}·{right arrow over (r)}){right arrow over (r)}−({right arrow over (r)}·{right arrow over (r)}){circumflex over (v)})/{right arrow over (r)}·{right arrow over (r)}. In embodiments the arrays are comprised in magnetic resonance machines. In embodiments the polyhedral magnets are truncated cubes or are rhombic dodecahedra.
