摘　　要：本文分别利用毕奥-萨伐尔定律和磁矢势对不同密绕程度下载流螺线环的磁场进行了理论计算,并对其进行了MATLAB仿真,结果表明载流螺线环的磁场分布具有随距离变化的跃变特征、随角度变化的周期特征和随密绕程度的振荡特征.Based on the Biot-Savart law and the magnetic vector potential,this paper calculated strictly the magnetic field of current-carrying ring solenoid with different density.The MATLAB simulation results show that the magnetic field of the circular current solenoid has the characteristics of jump with distance,periodic variation with angle and oscillation with density.
