摘要：

A　three-dimensional　field　solutions　are　presented　for　Halbach　cylinder　magnet.　Based　on　Ampere　equivalent　current　methods,　the　permanent　magnets　are　taken　as　distributing　of　current　density.　For　getting　the　three-dimensional　field　solution　of　ideal　polarized　permanent　magnets,　the　solution　method　entails　the　use　of　the　vector　potential　and　involves　the　closed-form　integration　of　the　free-space　Green＇s　function.　The　programmed　field　solutions　are　ideal　for　performing　rapid　parametric　studies　of　the　dipole　Hal-b　ach　cylinder　magnets　made　from　rare　earth　materials.　T　he　field　solutions　are　verified　by　both　an　analytical　two-dimensional　algorithm　and　three-dimensional　finite　element　software.　A　rapid　method　is　presented　for　extensile　analyzing　and　optimizing　Halbach　cylinder　magnet.
