CHINA: On August 12, the hybrid magnet at the Steady High Magnetic Field Facility (SHMFF) in Hefei, China, created a steady magnetic field of 45.22 Tesla’s (T), breaking the previous record for the strongest steady magnetic field by a functioning magnet.

It surpassed the previous world record of 45 Tesla’s, which had been set in 1999 by a hybrid magnet at the United States National High Magnetic Field Laboratory.

This 45.22-Tesla hybrid magnet consists of a resistive insert nestled inside a 32-mm-bore superconducting outsert. The hybrid magnet was created in 2016 by the Hefei team. It was the second 40-Tesla-level magnet in the world at the time and produced a 40-Tesla central magnetic field.

According to Prof. KUANG Guangli, academic director of the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science, Chinese Academy of Sciences (CHMFL), which is home to SHMFF, “we innovated the structure of the magnet and developed new materials to achieve higher magnetic fields.” In a declaration given during an on-site evaluation by seven CAS members, KUANG said that “the production process for the Bitter discs was also optimised.”

The 45.22-Tesla magnet’s accomplishment marks a significant turning point in both China’s and the world’s advancement of magnetic technology.
One of the ten magnets that CHMFL has created and is now using is this one. Three world records were previously set by the Hefei laboratory using resistive magnets.

Since its inception, the SHMFF user facility has operated for more than 500,000 machine hours, providing over 170 institutions or universities domestically and abroad with the experimental conditions for cutting-edge research in a variety of fields. SHMFF is now the world’s strongest steady-state magnetic field.
