The　analysis　of　magnetic　particle　dynamics　in　a　rotating　magnetic　field　and　the　exploration　of　the　magnetic　agglomeration　mechanism　are　crucial　for　effectively　reducing　agglomeration　in　strong　magnetic　minerals　and　improving　sorting　efficiency.　The　forces　acting　on　magnetic　particles　in　a　rotating　magnetic　field　were　analyzed　in　this　study.　A　3D　model　was　built　to　simulate　the　complex　interaction　between　two　magnetic　particles　in　a　rotating　magnetic　field　using　COMSOL　Multiphysics　finite　element　simulation　software.　It　shows　that　the　number　of　periods　of　change　in　the　spiral　period,　velocity,　and　acceleration　remains　consistent　under　different　conditions.　Additionally,　their　period　numbers　are　positively　correlated　with　magnetic　field　rotational　speed,　medium　viscosity,　and　the　initial　particle　spacing,　and　negatively　correlated　with　magnetic　field　strength.　Under　various　conditions,　the　larger　the　area　of　the　velocity-closed　surface　in　the　same　cycle,　the　larger　the　helical　diameter　of　the　particle　trajectory.　The　initial　acceleration　of　the　particles　exhibits　a　positive　correlation　with　the　strength　of　the　magnetic　field,　a　negative　correlation　with　the　viscosity　of　the　medium　and　the　initial　distance,　and　no　significant　relationship　with　the　rotational　speed　of　the　magnetic　field.　For　further　research　on　the　dynamics　of　magnetic　particles　and　the　refinement　of　the　mechanism　of　magnetic　agglomeration,　the　results　have　an　important　theoretical　reference　value.
