摘　　要：磁偶极子是电磁物理领域的一个重要概念,是类比电偶极子而建立的物理模型,通过一段封闭回路电流来描述磁场的源和分布特性。本文介绍了磁偶极子近年来的研究进展,分析了磁偶极子模型的适用性与局限性,重点评述了其在颗粒间相互作用力、磁定位、矿粒的团聚与分离、无损检测等领域的应用现状,并展望了未来磁偶极子模型应用研究的重点方向。Magnetic dipole is an important concept in the field of electromagnetic physics,which is a physical model established by analogy with electric dipole.The source and distribution characteristics of magnetic field are described by a closed loop current.This article introduces the research progress of magnetic dipoles in recent years,analyzes the applicability and limitations of magnetic dipole models,focuses on reviewing their application status in the fields of particle interaction forces,magnetic positioning,agglomeration and separation of mineral particles,non-destructive testing,etc.,and looks forward to the key directions of future research on the application of magnetic dipole models.
