磁靴开孔对磁场影响的理论计算与实验研究

为满足实验要求 ,必须在产生均匀磁场的磁靴上开一个观察孔 ,这样磁场均匀度势必会受到影响。本文介绍了均匀磁场的设计方法并进行了具体设计 ,对开孔带来的影响进行了数值模拟。利用有限元法分析了磁场均匀性与边界条件之间的关系并给出了具体的磁场分布数据表图。在理论分析的基础上 ,进行了实验验证 ,最后得到了满足设计要求的均匀磁场

Theoretical and Experimental Research of the Drilled Magnetic Field

To meet the needs of experimental research, a hole must be drilled on the magnetic iron, which will affect the uniformity of the magnetic filed. A uniform magnetic field is designed and theoretical analysis of the distribution of the magnetic field is presented. The relation between boundary condition and uniformity of the magnetic field is discussed in detail and plotted into graph. Available and new experimental data are discussed on the basis of this theoretical analysis. This treatment leads to an enhanced understanding of the drilled magnetic filed.
