摘 要: 直接从载流直导线的磁感应强度公式出发,利用极限的思维方法,分析出任一段载流圆弧导线在轴线上一点产生的磁感应强度表达式,并得出圆电流轴线上的磁感应强度. Based on the magnetic induction intensity formula for the carrying straight current wire and by using limit method, we deduce the expression of the magnetic induction intensity for a point in the axes of an arc wire carrying current, and obtain the formula of the magnetic induction intensity of the axes for the circular current.
