With　increasing　applications　of　permanent　magnetic　materials　in　magnetic　levitation　system,　comprehensive　understanding　of　the　field　around　the　permanent　magnetic　materials　becomes　more　and　more　important.　For　the　stationary　magnetic　field　of　rectangular　permanent　magnet,　the　paper　gave　the　spacial　distributions　of　it　by　experimental　method　and　analyzed　the　distribution　characteristics　in　three　dimensions.　The　numeric　distributions　of　ponderances　in　magnetization　direction　and　in　vertical　direction　of　magnetization　of　single　magnet　along　different　coordination　were　given.　Furthermore,　the　paper　worked　out　spatial　distribution　statures　and　characteristics　of　all　the　ponderances　of　repultive　magnets　and　attractive　magnets,　and　testified　the　overlapping　attribute　of　magnetic　vector　in　space.
