用格林定理求解磁矢势A

Magnetic vector potential solved with the use of Green′s theorem

磁矢势在理论物理中是一个重要的物理量 ,文章通过简单的数学分析 ,利用格林定理求解磁矢势 A,获得任意场域中磁矢势 A的积分计算公式 ,并利用无穷远边界条件获得无界空间中磁矢势 A的计算公式。

Using the Green′s second integral identity with the vector form,the integral solution of magnetic vector potential A is introduced in the arbitrary field domain,some problems related with Electrodynamics teaching are also discussed.
