摘　　要：悬浮磁阱可以很好地消除磁阱盲鳗线圈支撑结构上的等离子体流失,进而提高磁阱对等离子体的约束效率。文中以Galatea型磁约束装置四极悬浮磁阱为研究对象,提出了四极悬浮磁阱盲鳗线圈所受电磁力的计算方法,并利用COMSOL建立四极悬浮磁阱的电磁仿真模型,分析各线圈距离与电流变化对线圈所受电磁力的影响,对悬浮磁阱的设计意义重大。The levitating magnetic trap can eliminate the plasma loss of the magnetic trap blind eel coil support structure, and then improve the confinement efficiency of the magnetic trap to the plasma. In this paper, the quadrupolelevitation magnetic trap of the Galatea magnetic confinement device is taken as the research object, the electromagnetism force＇s calculation method of blind coils is proposed, the electromagnetic simulation model of quadrupole-levitation magnetic trap is established by COMSOL, the influence of distance and current of the coil on the electromagnetic force of the coil is analyzed, which is of great significance to the design of the suspension magnetic trap.
