摘要
直接从毕奥—莎伐尔定律写出圆线圈在空间任一点磁场分量的积分表达式 ,通过数值计算给出其分布曲线 ,进一步给出亥姆霍兹线圈的磁场分布曲线 ,非常直观。该文还讨论了探测线圈直径对测量精度的影响 。
The integration equations about the magnetic field of circular current loop are given directly by Biot-Savart's Law. Through numerical calculation of these equations, the distribution curves of the circular current loop and the Helmhoitz loop magnetic fields are presented. The influence of the diameter of detecting loop on the accuracy is discussed and the even range of magnetic field about Helmhoitz loop is offered here.
