| 摘 要： | 长直螺线管中变化的磁场是产生涡旋电场的源，涡旋电场也将反作用于磁场．在一般情况下，磁场的分布不是均匀的。文中指出了一般教材中假定磁场均匀分布的条件，推导出了一般情况下的磁场分布曲线，并进一步讨论了交变电磁场用频率及导休时磁场分布的影响。

| Abstract: | It is well-known that alternating magnetic field is the source of eddy electric filed in long and straight coils.The eddy electric field will react to the alternating magnetic field. In general,the distribuiton of magnetic field is not uniform. In this paper,the condition of the uniform magneitc field is studied and the distribution curve of magnetic field in general situation is figured out. In the concusion,the influence of the angular frequency of alternating electronmanetic field and conductor on the distribution of magnetic field are discussed. |
