We demonstrate a technical solution to achieve an intense 50 Hz alternating magnetic field and a static magnetic field made by a permanent magnet at the same place. A compact coil built using the Bitter coil concept is customized to support alternating current, thus creating an alternating magnetic field. A complementary permanent magnet assembly is built around it to achieve the superposition of both fields along the axis of symmetry. Results from the experimental model are compared to both numerical and analytical models.

由感应线圈和永磁体组成 50 Hz 交变和静磁场的系统设计

我们展示了一种技术解决方案，可在同一位置实现由永磁体产生的 50 Hz 强交变磁场和静态磁场。使用 Bitter 线圈概念构建的紧凑型线圈经过定制以支持交流电，从而产生交变磁场。一个互补的永磁体组件围绕它构建，以实现两个磁场沿对称轴的叠加。实验模型的结果与数值和分析模型进行了比较。
