Magnetic　separation　is　a　primary　method　for　processing　iron　ore　and　plays　a　crucial　role　in　both　current　beneficiation　practices　and　other　fields.　Extensive　research　has　been　conducted　on　the　motion　behavior　of　magnetic　particles　within　magnetic　separation　equipment.　However,　force　analysis,　particularly　the　calculation　of　magnetic　forces,　remains　imprecise　when　dealing　with　irregularly　shaped　particles.　Accurate　prediction　of　magnetic　particle　behavior　requires　precise　magnetic　force　calculations.　This　study　introduces　micromagnetic　simulations　to　accurately　compute　the　magnetic　forces　on　irregular　magnetic　particles.　Micromagnetic　simulations　can　determine　the　precise　magnetic　moments　and　magnetic　induction　intensities　within　each　microelement　of　the　particle.　The　results　of　these　simulations　will　be　validated　using　magnetic　force　microscopy　(MFM).　The　findings　indicate　that　traditional　magnetic　force　calculations　deviate　from　the　precise　calculations　presented　in　this　study.　For　irregular　particles,　the　computational　errors　in　repulsive　and　attractive　forces　are　770%　and　576%　higher,　respectively,　compared　to　spherical　particles.　This　underscores　the　necessity　of　considering　particle　shape　in　realistic　magnetic　force　calculations.　Additionally,　both　the　MFM　measurement　images　and　the　simulated　magnetic　force　maps　exhibit　bright　and　dark　regions　correlated　with　particle　shape,　demonstrating　that　micro-　magnetic　simulation　results　can　be　verified　through　MFM　measurements.　This　paper　proposes　an　experimentally　verifiable　method　for　accurately　calculating　the　magnetic　forces　on　magnetic　particles　using　micromagnetic　simulations,　which　holds　significant　implications　for　designing　more　efficient　and　precise　magnetic　separation　equipment.
