摘要
本文介绍了螺线管无矩线圈的原理、磁场分布计算方法,对无矩线圈与普通螺线管线圈的内部磁场均匀性和外部磁场衰减进行了比较,并对不同长径比、不同内外径比的无矩线圈的内部磁场均匀性和外部磁场衰减进行了分析。
In this paper,the writer introduces the theory of solenoid non-moment coil and calculation method of magnetic field distribution,and compares the internal magnetic field uniformity and external magnetic field attenuation between non-moment coil and normal solenoid coil.In addition,it analyzes the internal magnetic field uniformity and external magnetic field attenuation of non-moment coils in different length-diameter ratio and different internal-external diameter ratio,and the analysis and comparison conclusion is given for reference in the design of non-moment coil in shielding cylinder
