本文研究了计算超导磁体磁场的不同模型。精度和计算时间进行了比较，为一系列不同的简化模型：电流回路和薄壳螺线管，并与有限的长度和厚度。“什么模型是最好的”没有明确的答案，因为它取决于特定的用例，但有一些模型在速度或准确性方面表现出色，还有一些模型的使用非常有限。本文作为一个概述，将帮助读者作出明智的选择的模式。
This paper examines different models for calculating the magnetic field of solenoids. Accuracy and computation time are compared for a range of different simplified models: a current loop and a thin shell solenoid, and solenoids with finite length and thickness. There is no definitive answer to "what model is the best", as it depends on the specific use case, but there are certain models that excel in speed or accuracy, and there are models that have very limited use. This paper serves as an overview and will help the reader make an informed choice of a model.
