Reporters learned from Hefei Institute of Physical Sciences, Chinese Academy of Sciences that on August 12, the national major scientific and technological infrastructure "Steady-state Strong Magnetic Field Experimental Device" achieved a major breakthrough, creating a steady-state strong magnetic field with a field strength of 452,200 Gauss, surpassing what has been maintained It has set the world record of 450,000 Gauss steady-state strong magnetic field for 23 years. An expert group composed of several academicians of the Chinese Academy of Sciences and the Chinese Academy of Engineering concluded that the results have reached the international leading level.

Strong magnetic field is an extreme experimental condition for exploring the frontiers of science. It plays an irreplaceable role in discovering new phenomena and giving birth to new technologies. Since 1913, major achievements have been made in the fields of high-temperature superconductivity, quantum materials, and life sciences. It was found that about 20 related results have won Nobel Prizes.

Steady-state strong magnetic field experimental device is a major national scientific and technological infrastructure project established by the National Development and Reform Commission during the "Eleventh Five-Year Plan" period. In 2017, it passed national acceptance and was officially put into operation, making our country one of the United States, France, Netherlands, , and Japan. Then the fifth country with a steady-state strong magnetic field. How strong is

45.22 million Gaussians? According to reports, the earth's magnetic field is approximately equal to 0.5 Gauss, and the new record is equivalent to more than 900,000 times the earth's magnetic field. Just like a microscope can see more clearly when magnified 100 times than when magnified 10 times, the stronger the magnetic field, the more helpful it is to explore the internal structure of matter, providing better conditions for humans to discover the laws of nature and develop new technologies.

It is understood that since the steady-state strong magnetic field experimental device was put into use, it has operated for more than 500,000 machine hours, providing experimental conditions for more than 170 scientific and educational institutions at home and abroad, supporting scientific researchers in physics, chemistry, materials, life, More than 3,000 cutting-edge research projects have been carried out in engineering technology and other fields, and a series of important scientific research breakthroughs have been achieved. source: Xinhua News Agency
