中文摘要：

利用Matlab软件对多螺线管磁场分布趋势及强度进行了研究,计算结果表明当各个螺线管通以同向电流时,各个螺线管相对几何中心处磁感线相互排斥,且磁场强度变小,当在4个螺线管几何对称中心轴正上方再放置一个螺线管时,各个螺线管产生的部分磁感线会沿着正上方放置的螺线管磁感线方向行走且当计算选取微元和步长越小结果越准确.

英文摘要：

Magnetic field distribution and intensity of multi-solenoid was calculated with Matlab. Data showed that center of each solenoid magnetic field lines were mutual repulsion and magnetic field intensity became smaller, when the solenoid was introduced with same direction current; Part of the magnetic field lines generated by 4 different solenoids would go in direction of the above placed solenoid＇s magnetic field lines when a solenoid was placed above center axis of symmetry of four solenoids. The smaller micro element and step length, the more accurate the calculation result was.
