疏绕有限长恒定电流圆柱形螺线管磁场的空间分布

摘要

用数值分析的方法研究疏绕有限长恒定电流圆柱形螺线管磁场的空间分布。分析了中心区域磁场的均匀度，并与密绕有限长恒定电流圆柱形螺线管的磁场作比较。%The spatial distribution of the magnetic field from a spaced winding finite-length steady current cylindrical solenoid is numerically investigated by using the mathematical software.The uniformity of this magnetic field is analyzed,and is compared with that of the magnetic field of the tightly wound cylindrical solenoid.
