In　order　to　solve　the　problem　of　the　force　field　distribution　of　the　rectangular　permanent　magnet,　the　method　of　theoretical　analysis　and　numerical　analysis　is　used.　The　equation　formulation　for　the　force　and　the　torque　field　of　the　interactive　dipole　triads　is　obtained.　The　results　show　that　the　formulation　of　the　magnetic　force　and　torque　distribution　for　the　rectangular　permanent　magnet　in　this　paper　can　give　access　to　the　precise　three-dimensional　magnetic　force　and　torque　field　distribution　surrounding　double　permanent　magnets　which　arranged　in　different　manners　and　in　different　position.　The　magnetic　force　field　characteristic　discussed　in　the　simulation　of　magnetic　field　can　provide　a　theoretical　base　for　engineering　application　and　the　magnetic　track　field　control　of　permanent　magnets.
