摘要
导出了电流元的磁力线方程 ,发现任一磁力线是一闭合圆线 ,圆心在三个坐标平面上沿直线变化 。
The equation of magnetic line of force for current element is derived and the concluion is obtained that any magnetic line of force is a close circle and its center changing in straight line on three coordinate plane, the oblique rate is determined by current element.
