摘　　要：本文从毕—萨定律出发通过利用对称性和椭圆积分的方法比较简单地得出椭圆载流线圈轴线上的磁场分布,它比一般教科书上的圆形载流线圈的磁场分布更具一般的意义。Proceeding from Biot-Savart law,this paper obtains the distribution of the magnetic field on the axis of the elliptic current-carrying coil in a comparatively simple way by means of symmetrical characteristic and elliptic integral,and this contribution is of more general signgficance than that of spherical current-carrying coil described in ordinary textbooks.
