This　paper　in　magnetic　troduces　some　research　results　about　the　magnetic　characteristics　on　soft　composite　(SMC)　material.　Based　on　the　mechanisms　of　magnetic　material　magnetization,　a　vectorial　hysteresis　model　is　proposed　to　simulate　the　hysteresis　characteristics　of　SMC　material.　Meanwhile,　by　using　the　three　dimensions　magnetic　properties　test　platform,　the　magnetic　features　of　SMC　material　under　different　applied　magnetic　fields,　such　as　alternating　field　and　rotational　field,　have　been　measured.　To　verify　this　presented　vectorial　hysteresis　model,　a　given　SMC　material　is　employed　to　be　simulated　and　measured　under　rotating　and　alternating　excitations,　respectively.　Compared　with　the　two　results,　a　good　agreement　can　be　obtained,　which　shows　the　validity　and　practicability　of　the　proposed　hysteresis　model.　©　2021,　Beijing　Oriental　Sun　Cult.　Comm.　CO　Ltd.
