计算载流圆线圈空间磁场分布的方法

用毕－萨定律通过矢量运算和几何关系导出圆电流磁场空间分布的积分表达式，使用计算机通过数值积分计算其数值，进一步讨论圆电流平面内和垂直ｚ轴平面内磁感应强度按径向分布，并分别给出磁场分布曲线。

A Method of Calculating Magnetic Fields Distribution within the Space of a Circular Coil Carrying Current

Applying Biot-Savarts Law to have calculated vectors and their geometric relation, an integral formula is deriv ated therefrom, expressing magnetic fields distribution within a circular current space, and here in numericals are found by means of numerical sintegrated calculation with computers. As the result, a further discussion is made on the induced strength shown within both the plane in relation to the circular current and the plane vertical to zaxis, i.e, this streng this distributed along a radial direction. These curves indicating megnetic fields distribution are also proposed respectively.
