Magnetic　intelligent　compound　which　is　a　composite　polishing　material　of　magnetic　particles,　abrasives　and　adhesive　can　be　solidfied.　Its　polishing　performance　is　to　a　large　extent　affected　by　the　distribution　of　particles.　Since　the　polishing　performance　of　this　material　is　based　on　the　distribution　of　particles,　the　effects　of　applied　magnetic　field,　particles　density,　and　the　size　of　particle　cast　on　the　distribution　of　MAGIC　particles　is　studied　in　this　paper.　The　results　showed　it　is　easier　for　magnetic　particles　to　form　cross　and　cluster　chain,　given　strong　applied　magnetic　field,　small　size　of　magnetic　particle,　and　high　magnetic　particle　density.　Otherwise,　short　chain　is　easier　to　form.
