摘要
本文在电动力学的范围内,对该“毕奥-沙伐尔定律”成立的条件、与安培环路定理之间的关系,特别是考虑位移电流后毕-沙定律的形式、实质等问题作了深入的研究。
Biot-Savart law is one of the important laws in electromagnetics.This article,within the framework of electrodynamics,discusses the conditions for the tenability of the“law”,and the relations between the“law”and the“Ampere circuital theorem”。It especially maskes a deep study of the problems on the Biot--Savart law's forms.essence and so on after thinking of displacement current.
