摘要

用测量的方法获得磁场分布规律

结果表明

磁场在感应线圈内较大

向两端衰减;轴向磁场随功率的增加而增大

随半径的减小而减小

从开缝处向瓣内减小

不过减小不明显;径向磁场随半径减小急剧减小

随线圈匝数增加而减小。轴向磁场大于径向磁场

对电磁约束成形起主要作用的是轴向磁场。

Abstract

Distribution of magnetic strength is measured by the small induction coil method.The results show that the magnetic strength is higher inside the coil

and then is attenuated toward both ends.Axial magnetic intensity increases with the increases of the power

and decreases with the decrease of the radial

slightly decreasing from the slit to the middle of the segment.Radial magnetic intensity is sharply decreased with increasing in radius and coils.Axial magnetic intensity is higher than radial magnetic intensity

and is more important for electromagnetic confinement.
