摘要
大学物理教材中只研究了圆形电流轴线上一点的磁感应强度 B ,而对圆面内任意一点的磁感应强度 B却未给出计算公式 .本文运用毕奥—萨伐尔定律及西普森公式 。
The college physics teaching materials have only studied a little magnetic induc tion on the axis of the roun d electric current,have not provided the formula of calculating to the magnetic induction that the round on e is inside a bit more wanton, after Biot-Savart law of trees formula can draw w anton magnetic induction expression formula of intensity a bit inside the round electric current.
