An all-superconducting magnet developed by Chinese scientists has recently achieved a world-record steady magnetic field strength of 35.1 tesla, a breakthrough which provides key technological support for multiple industrial applications, including magnetic resonance imaging (MRI), aerospace electromagnetic propulsion, superconducting magnetic levitation (maglev) and high-efficiency power transmission, China Central Television (CCTV) reported on Sunday. 

The superconducting magnet developed under the leadership of the Institute of Plasma Physics, Chinese Academy of Sciences, in collaboration with several other domestic research institutions and universities, adopts a combined design of high-temperature plus low-temperature superconducting magnets, which are precisely nested to create a stable composite structure. 

Researchers have enhanced the magnet’s mechanical stability and electromagnetic performance under extreme conditions.

In tests, the magnet reached 35.1 tesla and ran stably for 30 minutes, verifying the technology’s reliability. It is expected to provide a strong platform for conducting experiments under ultra-high magnetic fields. 

This achievement marks a breakthrough in key technologies facing the international community in the field of ultra–high-field, all-superconducting steady-state magnets, achieving 100 percent independently developed and controlled over critical materials, processes and fabrication. 

This achievement is expected to drive technological upgrades in China’s high-temperature superconducting materials industry, and provides key technological support for industrial applications across multiple fields, including magnetic resonance imaging, aerospace electromagnetic propulsion, superconducting induction heating, superconducting magnetic levitation (maglev), and high-efficiency power transmission.
