摘要
安培环路定理是稳恒磁场性质的重要方程,它反映了磁感应线的特点:磁感应强度沿磁感应线的环路积分不等于零.有些教科书中对该定理叙述不准确,造成求解电流产生磁场的问题中出现某些错误.本文对安培环路定理给以准确的说明和详细的论证.
The Ampere＇s Circulation Theorem is an important field equation in stable magnetic field. It refleets the point of magnetic induction lines, which means the circulation integral of magnetic induction along the magnetic lines is not zero. Inaccurate statements of this theorem usually occur in some teaching materials, which bring some mistakes in solving the problem of electric current making magnet field. In this essay, the Ampere Circuital Theorem is accurately illustrated and detailed exact demonstration is made upon it.
