       For a long time, people have been seeking the best design scheme of solenoids, hoping to produce more high-quality and low-cost solenoids. In the traditional design methods of solenoids, people try to use various mathematical and experimental methods to find the most reasonable proportion between the various sizes of solenoids. However, due to the limitations of relevant theories, mathematical methods, and computational methods, these optimal proportional relationships can only be partial, and are mostly based on qualitative analysis. The optimization design of solenoids has been gradually developed since the advent of electronic computers, which has truly been applied in engineering. In fact, electronic computers are important tools for optimal design of solenoids in engineering practice. It is precisely because of the high-speed computing and logical judgment capabilities of computers, as well as the storage capacity of a large amount of data information, that engineering designers can calculate and analyze various characteristics of solenoids from multiple aspects, and achieve quantitative and accurate calculation of these characteristics, which also lays a solid foundation for the optimal design of solenoids.

       The continuous improvement of electromagnetic theory and mathematical methods has also promoted the development of optimal design of solenoids, especially the application of optimization methods, making it possible to seek some (some) optimal economic and technical indicators under certain design requirements.

       Overseas research on the optimization design of solenoids began in the mid-1960s. At that time, the main topic was to discuss the single variable optimization design problem, and the application of computers mostly belongs to auxiliary calculation. Subsequently, mathematical programming was gradually used to discuss global optimization problems with multiple variables. Among them, the Soviet Union, the Federal Republic of Germany, France, Japan, and other countries not only have carried out work on the optimization design of solenoids, but also have begun to apply a large number of optimization designs to the design of electrical products. For example, the electromagnetic systems of the 13 specifications (10 to 600A) of Toshiba Electric Co., Ltd.'s new EPAR series magnetic starter are all optimized in design.

         In the late 1970s, China began research work on the optimal design of solenoids, mainly focusing on relevant universities and research institutes. In recent years, solenoid optimization design has been gradually applied to engineering design, and has achieved good economic and social benefits.
