以多丝和单丝镁B2丝为基础，设计并研制了内径约32 mm的恒流工作磁体。该磁体为多螺线管结构。一个导引线圈被缠绕，两端都制造了接头，将其连接到超导开关上，用于PC操作测试。该磁体用于展示在不同温度下的高场和高温性能。数值计算和实验结果表明，该材料在低成本磁共振成像(MRI)系统和高场科学磁体中具有广阔的应用前景。
Persistent current (PC) operating magnet with bore diameter of about 32 mm was design and developed based on multi- and mono-filament MgB2 wires. The magnet was in a multi-solenoid structure. One pilot coil was wound and joints were fabricated at both ends, connecting it to a superconducting switch for PC operation tests. The magnet was to demonstrate the high field and high temperature performance at different temperatures. Numerical and experimental results demonstrated a promising future of MgB2 wires in low cost magnetic resonance imaging (MRI) systems and high field scientific magnets.
