| 摘 要： | 不少物理实验仪器应用了亥姆霍兹线圈的均匀磁场区,但缺乏必要的使用限制性。本文依毕奥—萨伐尔定律推导出该线圈区域内任意点磁感应强度的积分公式,用计算机进行了数值计算,画出等值线图。并由此确定出允许误差所对应的均匀磁场区,为使用限制性提供了依据。还通过理论分析肯定了中心点磁场的二阶均匀性。

| Abstract: | The uniformly distributed region of the magnetic field of Helmholtz coils has been used in many instruments for physical experiments without definite limitation. In this article the integral formula of the magnetic induction at any point in the region of given coils has been derived from the Biot-Savart law.The calculation of the values has been carried out by the computer, and the drawing of the equivalent line has been made over it. Therefore, the uniformly distributed region can be confind with the opposite allowance error.Through the theoretical analysis, it was confirmed that the magnetic field has the twi-order uniformities in any directions near the central point of the Helmholtz coils. |
