摘要
采用将圆电流磁矢势表达式中一部分展成级数 ,使被积函数变成可积分的函数 .用解析函数拟合积分后的级数 ,代替无穷级数求和运算 ,得到可以计算圆电流在空间任何一点磁场的解析解 .
A part of results on magnetic vector potential of circular loop are expanded, so the integral function is transformed to integrable series. The series are fitted with analytical function which can replace sum of infinite series. The magnetic field of circular loop at any point is obtained. The problem of calculating non-adaxial magnetic field of circular loop is solved.
