Overview

• The Institute of Plasma Physics of the Chinese Academy of Sciences in Hefei reported a stable 351,000‑gauss field, surpassing the previous 323,500‑gauss record.
• The fully superconducting device held 35.1 tesla for 30 minutes and was safely demagnetized, according to reports citing Xinhua and China Daily.
• The architecture inserts a high‑temperature superconducting coil coaxially inside low‑temperature superconducting magnets to manage stress and multi‑field coupling.
• Project participants included Tsinghua University and Hefei research institutions, as detailed in the coverage.
• Researchers say the advance could speed commercialization of superconducting instruments and support applications in fusion magnets, NMR/MRI, maglev transport, space electromagnetic propulsion, and efficient power transmission.
