摘要
应用已导出的磁各向异性介质中的毕奥-萨伐尔定律的极坐标形式,求出用极坐标方程表示的圆电流内部的磁场,并证明其磁场在圆电流中心具有最小值.
The magnetic field in circular current expressed by polar equation can be solved by applying the derived polar coordinate form of the Biot-Savart law in magnetic anisotropic medium. The magnetic field with a minimum at the circular center has been verified.
