毕奥萨伐尔定律的极坐标形式及应用

The Formation and Application of Polar Coordinates of Biot--Savart Law

文中给出当电流置于平面上时 ,毕奥萨伐尔定律的极坐标形式 .利用此形式给出几种特殊形状载流导线在空间一点的磁场 .

This paper offers the formation of polar coordinates of Biot--Savart law when the electric current is put on the plane .With the help of this formation , it shows the magnetic field of the currentcarrying lead which has several special shapes in the space.
