满足特定要求的磁线圈广泛应用于现代量子物理学。在这项研究中，提出了一种设计用于产生任意轴向磁场的屏蔽线圈的通用分析方法。获得了单个屏蔽线圈产生的轴向磁场的理论公式，并将其用于构造特定的线圈。这些线圈的结构参数是通过理论公式与其具体要求的拟合来确定的。通过实现均匀磁场产生线圈、梯度磁场产生线圈、非对称均匀磁场产生线圈和抛物线磁场产生线圈四种具体线圈，证明了该方法的可行性。有限元模拟和相关实验结果证明了这些理论结果的正确性。此外，该方法的应用对于未来量子物理和量子器件的发展具有重要意义。
Magnetic coils for specific requirements are widely used in modern quantum physics. In this study, a general analytical method of designing the shielded coils for generating an arbitrary axial magnetic field is proposed. The theoretical formula for an axial magnetic field generated by a single shielded coil is obtained and used to construct specific coils. The structural parameters of these coils are determined by fitting the theoretical formula with their specific requirements. The feasibility of this method is proved by realizing four concrete kinds of coils: uniform magnetic field generating coils, gradient magnetic field generating coils, asymmetrical uniform magnetic field generating coils, and parabolic magnetic field generating coils. The correctness of these theoretical results is demonstrated by both the finite element simulations and the relevant experimental results. Furthermore, the application of this method is of great significance for developing the quantum physics and quantum devices in future.
