摘要
基于磁各向异性介质中的毕奥—萨伐尔定律的极坐标形式,首次推导了极坐标方程表示的载流圆线圈外部磁场的精确解.图示了磁感应强度的变化情况,并结合精确解和图形得到了磁各向异性介质中载流圆线圈外部磁场的分布特点.
Based on the polar coordinate form of the Biot-Savart law in magnetic anisotropic medium, the exact solution of the magnetic field out of the circular current expressed by polar equation were deduced. The patterns of the magnetic induction intensity B were drawn, and according to the exact solution and patterns, the distribu- tion characteristics of Magnetic induction were obtained.
