用磁场的高斯定理求解磁力线方程

Solution of the Equation of the Magnetic line Of Force Using the Magnetic Version of Gauss's Law

本文以两无限长通电直导线为例，利用磁场的高斯定理求解磁力线方程．与传统方法相比，具有简捷、直观的优点，是求解磁力线方程的一种好方法．

The equation of the magnetic line of force, take two long straight current-carrying wires for example, is obtained using the magnetic version of Gauss's law in this paper. The result shows that this kind of solution is more simple and more objective as compared with any traditional ways.
