A set of Flux Core coils are used to generate the model interplanetary magnetic field in the SPERF (Space Plasma Environment Research Facility) device to simulate the magnetic reconnection on the magnetopause of the earth. Several technical challenges are imposed on designing the coils in terms of electricity, vacuum, support, and motion, etc. The design and the construction of the Flux Core coils are presented in the paper to overcome the difficulties. Based on the structure parameters and the magnetic forces, the Flux Core coils composed of a G10 (fiberglass laminate composite material) form and several other components are designed. A complex construction process is used to acquire high vacuum degree and reliable insulation as well as fine surface quality. A support structure with a dedicated buffer mechanism is designed, with the ability to resist the magnetic forces according to a mass-spring-damper model and the mechanical analysis. The Flux Core coils are being built based on the design and the tests will be done later.

一组磁芯线圈用于在 SPERF（空间等离子体环境研究设施）设备中生成模型行星际磁场，以模拟地球磁层顶上的磁重联。线圈的设计在电、真空、支撑和运动等方面面临一些技术挑战。本文提出了磁芯线圈的设计和构造以克服这些困难。基于结构参数和磁力，设计了由G10（玻璃纤维层压复合材料）形式和其他几个组件组成的磁通芯线圈。采用复杂的施工工艺，获得高真空度和可靠的绝缘以及优良的表面质量。设计了带有专用缓冲机构的支撑结构，具有根据质量-弹簧-阻尼器模型和力学分析抵抗磁力的能力。Flux Core 线圈正在根据设计构建，测试将在稍后完成。
