摘要: 避开繁琐的椭圆积分推导,用微积分导出了圆电流在空间各点的磁感应强度的定积分公式,再变换成用椭圆积分表示的精确解.

关键词: 圆电流, 磁感应强度, 椭圆积分

Abstract: Avoid the fussiness elliptic integral method, firstly the magnetic induction density of the circular current is derived tersely by the calculus, and then it is turned to the formulas for the magnetic induction of the elliptic integral.

Key words: circular current, magnetic induction density, elliptic integral
