　　Chinese researchers have successfully developed an all-superconducting user magnet with a central magnetic field strength of 35.6 teslas – more than 700,000 times that of Earth’s magnetic field – setting a new world record for all-superconducting user magnets, the Xinhua news Agency reported on Tuesday.

　　The breakthrough marks China’s attainment of internationally advanced capabilities in high-temperature superconducting applications and is expected to provide strong technical support for research in materials science, life sciences and nuclear fusion, among other fields, per Xinhua.

　　According to CCTV News, the all-superconducting user magnet, which uses a high-temperature superconducting insert magnet as its core, has a bore diameter of 35 millimeters. It first achieved a magnetic field of 30 teslas in 2023 and has since been opened to domestic and international users.

　　Following continuous upgrades to materials, structure and manufacturing processes, the research team recently raised the maximum magnetic field to 35.6 teslas while keeping the bore size unchanged.

　　With this achievement, the system has become the world’s only all-superconducting user magnet capable of providing magnetic fields above 30 teslas for materials science research, significantly enhancing China’s strength in strong-magnetic-field studies.
