摘 要: 本文根据毕奥-萨伐尔定律,对矩形截面的通电密绕弯曲螺线管产生的磁场进行了理论推导,并得到了相应的解析解.然后利用Matlab编程计算,展示了3种典型环状螺线管的磁场分布特点,并对其中半环状结构的管内场分布特点做了深入讨论. According to the Biot-Savart law,we derive the magnetic field of the current-carrying tightly wound bent solenoid with the rectangular cross section,and obtain the analytic solution.Then,by using the Matlab software,the magnetic fields of three typical ring-shaped structures are shown,and the characters of the magnetic field in the semi ring-shaped structure are discussed in more details.
