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γ＝γ（θ）表示的圆锥曲线焦点的磁场，解决了用定律的笛卡儿坐标形式难以求解的问题．
The magnetic field at the focus of conical curve expressed by polar equation r=r(θ) can be solved by applying the derivated polar coordinate form of BiotSavart law in magnetic anisotropic medium. It solves the problem that is difficult to be solved by Cartesian coordinate form of the law.
