为了使永磁体偶极子产生高于磁性材料的剩余感应的场，Halbach和Stelter阵列是常用的结构。提出了一种新型强场永磁振子的设计方法。我们用电流片法对结构进行了分析。然后，我们使用了ANSYS软件来模拟结构。制作了一个偶极子原型。从原型偶极子的场进行了测量，并与分析和计算结果进行了比较。实际字段与计算结果非常匹配。没有明显的消磁效果。
For a permanent magnet dipole to produce fields higher than the remnant induction of the magnetic materials, Halbach and Stelter array are commonly used structures. This paper presents a novel design for strong field permanent magnet dipole. We analyzed the structure using current sheet method. We then used BEA software to simulate the structure. A prototype dipole was built. The field from the prototype dipole was measured and compared to the analytical and BEA results. The actual field matches the calculation very well. There is no visible demagnetizing effect.
