China’s 42-Tesla Resistive Magnet Technology Sets a New World Record

China’s creation of a potent 42-tesla resistive magnet has raised the bar globally. The nation has surpassed the 41.4-tesla mark that the US had held since 2017. The Chinese Academy of Sciences-affiliated Hefei Institutes of Physical Science’s High Magnetic Field Laboratory made the breakthrough on September 22. This breakthrough in magnetic field technology, which comes after years of study and structural advancements, puts China in the forefront of high-field magnet science and provides new instruments for material and scientific research.

A Major Technological Leap in Magnetism

The 42-tesla resistive magnet, which is powered by a 32.3 MW source, is evidence of China’s engineering prowess in this area. The Hefei lab’s feat comes after they achieved 45.22 teslas in 2022 with the strongest hybrid magnet in the world. The invention is the result of production and structural improvements during almost four years of consistent work. The end product was a magnet that could sustain a powerful, constant magnetic field. This makes it possible for a variety of scientific applications that depend on strong magnetic fields for investigation and learning.

Supporting High-Level Scientific Research

Researchers may now investigate materials and processes at extreme magnetic fields thanks to the new resistive magnet, which offers a sophisticated instrument for scientific inquiry. Strong magnetic fields like these are crucial for examining the basic characteristics of materials, which frequently results in physics and chemistry discoveries with practical uses, according to Guanli Kaung, academic director at CHMFL. Researchers can explore issues of material behaviour and atomic interaction with the use of high-field magnets.

China’s Position in Global High Magnetic Field Research

China now has specialised high-magnetic-field research labs, joining five other countries—the US, France, Japan, and the Netherlands. The field continues to be a focus of cutting-edge scientific research, with multiple Nobel Prize-winning discoveries arising from studies conducted in extremely magnetic environments. China’s recent performance demonstrates its dedication to advancing magnetic science and sets a high standard for future advancements in the discipline.
