摘　　要：作为求解载流导线周围磁感应强度的毕奥-萨伐尔定律,它的建立过程并非只是纯粹的实验,而是在毕奥的精巧实验基础上,再进行数学分析得到的结论.于是对毕奥-萨伐尔定律进行研究后发现,可以从一种简洁的分析方法得到此定律.Biot-Savart Law is used to calculate the magnetic field intensity around the current carrying conductor.Its establishment process is not only a pure experiment,but also a conclusion based on Biot's delicate experiment and mathematical analysis.Then this paper studies Biot-Savart Law and finds that this law can be obtained from a simple analysis method.
