我们提出了一个球形矢势线圈的模型，并研究了该线圈的性质，包括矢势的均匀分布。我们模拟了一种沿球面叠加环形细线圈的结构。不是沿着球体表面排列彼此紧密接触的环形线圈，而是环形线圈的层间距应该是恒定的，以便在球体轴线上的投影是相等间隔的。当电流施加到环形线圈时，在环形线圈之外不会产生磁场；相反，存在矢量势。当相同的电流通过每个环形线圈时，球体中的矢量势通过叠加实现了均匀分布。给出了二次导体通过线圈时矢量电势和感应电压分布的数值模拟结果。
We proposed a model for a spherical vector-potential coil and investigated the properties of the coil, including the uniform distribution of the vector potential. We modeled a structure in which thin toroidal coils are superposed along a spherical surface. Rather than arranging the toroidal coils in close contact with each other along the surface of the sphere, the layer spacing of the toroidal coils should be constant so that the projection onto the axis of the sphere is equally spaced. When a current was applied to a toroidal coil, no magnetic field was created outside the toroidal coils; instead, a vector potential was present. When the same current was passed through each toroidal coil, the vector potential in the sphere achieved a uniform distribution by superposition. We presented the results of our numerical simulation of the distribution of the vector potential and the induced voltage when a secondary conductor was passed through the coil.
