摘要直接由畢奧薩伐爾定律的計算公式，在更為普遍的情況下，計算出了圓形線電流在全空間的磁場分布，并進一步討論了其在中心軸線上、平面內及遠區的磁感應強度。
In the anistropic magic medium under the condition of magic permeabipty 11unequal to 33 , the magic field on axis pne of current - carrying coil and that inside current - carrying solenoid can be calculated by applying biot - savart law of that medium . as the condition of their service is restricted , it is necessary to derive the magic field on axial pne of current - carrying coil and that inside current - carrying solenod under more general condition of 11unequal to 33 . on the basis of the magic field on axial pne of current - carrying coil in anisotropic magic medium under the derived condition of 11unequal to 33 , the authors obtain the magic field on axial pne of current - carrying solenoid in anisotropic magic medium under general condition of 11unequal to 33 . the result shows a wider apppcable coverage
利用畢奧-薩伐爾定律，并在磁導率11 = 33的條件下，可求出各向異性磁介質中載流圓線圈軸線上的磁場，以及載流直螺線管內部的磁場.顯然，其使用條件受到限制.為此，有必要導出在11 33的更一般情況下，各向異性磁介質中載流圓線圈軸線上磁場和載流直螺線管內部的磁場.在已導出11 33及各向異性磁介質中載流圓線圈軸線上磁場的基礎上，求出一般情況下各向異性磁介質中載流圓線圈軸線上的磁場，使其結果適用範圍更廣
