摘　　要：文章依据亥姆霍兹线圈原理提出了一种多绕组结构的磁场发生器设计方案,利用Maxwell软件对其进行模拟仿真分析,并制作了一套多绕组磁场发生器。通过对比实际测量数值与模拟仿真数值,证明了该设备能产生0～2T的磁场,在中心区域磁感应强度的不均匀性小于3%,得到了预期效果。A new design of magnetic field generator with the multi-winding structure is put forward ac- cording to the theorem of Helmholtz coil. The Maxwell software is used to simulate and analyze the magnetic field, and a multi-winding magnetic field generator is designed and fabricated. The experimental results are compared with those of theoretical computing, and it is shown that this kind of magnetic field generator can produce magnetic field from 0 T to 2 T and the heterogeneity of magnetic induction in the central sector is less than 3%, so the anticipated result is obtained.
