摘要
通过对磁多极场的分析,其对称性可分为两大类:一类是二、六、十、十四、…极场,另一类是四、八、十二、十六、…极场.根据磁多极场的对称性,导出了磁多极场磁感应三个分量的泰勒级数展开式,定义了磁多极场的场参数.结果表明,通过 y 轴上 By 分量的数个参数,就可以近似计算得到整个空间的磁感应值.
There are two types of the symmetry for the magnetic multipole fields. According to the symmetry, Taylor series expansion formulae were derived from the magnetic multipole fields and field parameters were defined. The space magnetic field was obtained from the field parameters.
