传输线磁场分布研究

恒定电流周围产生的磁场会对生活在传输线附近人们的工作生活产生一定的影响。根据传输线形式的不同，电流大小的不同，磁场的分布及大小也不尽相同。文章针对三种不同形式的传输线，无限长直导线、无限长双导线和螺旋线分别计算了其磁场分布，就其分布规律做了比对研究。以期对传输线的设计、使用有所帮助。

Research on the Distribution of the Magnetic Field of the Transmission Line

Constant electric current will give birth to magnetic field, its existence is great menace to the people near the transmission line. Based on the different type of the transmission line and the current magnitude, the distribution and intensity of the magnetic field is dif- ferent. This paper researches the three types of the transmission line, single current conductor, double conductor and the loop（or coin）, con- trasts the field distributions. This paper is expected to be helpful to the design and use of the transmission line
