稳恒磁场安培环路定理的论述与推导

稳恒磁场安培环路定理是磁场的重要场方程,它反映了磁场的涡旋性及磁场与电流的关系,给出通过电流的分布求解具有某种对称性系口均匀性磁场的途径.文中准确地叙述了磁场安培环路定理,并对该定理给出了详细准确的论证,它克服了一些〈大学物理〉教材中关于磁场安培环路定理叙述的不准确问题,并避免了由于环路定理叙述的不准确而造成求解由电流产生磁场的某些错误,对进一步认识和理解磁场的性质将有所帮助,也给出用矢量场分析磁场性质的一种方法.

Comment and deduction of Amperecircuital theorem of stable magnetic field

The Ampere Circuital Theorem of stable magnetic field is an important field equation which reflects the vorticity of a magnetic field. In this essay, the Ampere Circuital Theorem is accurately illustrated and detailed exact demonstration is made upon it. Thus the problems of the inaccurate statement of this theorem that usually occur in some University Physics teaching materials have been solved. It is useful to further understand the properties of magnetic field, and presents a new way to analyze these properties by the means of vector field as well.
