China sets new record with 35.6 tesla all-superconducting magnet

China has achieved a new milestone in magnet technology by developing the world’s strongest all-superconducting user magnet, which generates a central magnetic field of 35.6 tesla—over 700,000 times stronger than Earth’s magnetic field. Built at the Synergetic Extreme Condition User Facility in Beijing, this magnet surpasses previous records for this class of equipment and offers a usable bore of 35 millimeters for direct experimental access. Its magnetic strength is 12 to 24 times greater than that of hospital MRI scanners, enabling researchers to study material behaviors under extreme conditions not replicable elsewhere. The magnet is designed as a shared research tool, open to both domestic and international scientists, supporting frontier research in materials science, life sciences, and other fields requiring strong, stable magnetic environments. The project was a collaborative effort among multiple institutes under the Chinese Academy of Sciences (CAS), with the Institute of Electrical Engineering leading the magnet’s design and manufacturing, and the Institute of Physics addressing system monitoring and
