Thanks to CTOnews.com netizens for the delivery of the clues of dream and snow season. According to the CCTV News today, according to the news of CTOnews.com8 on March 12, great progress has been made in the national steady-state high magnetic field experimental device developed by the strong Magnetic Field Science Center of Hefei Institute of material Sciences of the Chinese Academy of Sciences.

It is reported that the hybrid magnet with a 32mm magnet diameter has produced a steady magnetic field of 4522,000 gauss (that is, 45.22 Tesla), setting a new world record for the same type of magnet, which means that it has become the highest steady-state magnetic field that can support scientific research in the world.

Prior to this, the previous record was 450,000 gauss created by the National strong Magnetic Field Laboratory of the United States in 1999. 23 years later, this record was refreshed by China and became an important milestone in the construction of extreme conditions for scientific experiments in China and even the development of strong magnetic field technology in the world.

According to reports, the national steady-state strong magnetic field experimental device has operated more than 500000 machine hours, carried out more than 3000 cutting-edge research in the fields of physics, chemistry, materials, life and health, and engineering technology, and made many scientific research achievements, such as discovering the three-dimensional quantum Hall effect caused by Weir orbitals for the first time, revealing the molecular and neural loop mechanisms of solar irradiation to improve learning and memory.

As a "sharp weapon" to promote scientific progress, scientific and technological powers in the world attach great importance to the construction of experimental conditions for strong magnetic fields. at present, the five international steady-state high magnetic field laboratories are located in the United States, France, the Netherlands, Japan and Hefei Science Island in China.

CTOnews.com learned that the steady-state strong magnetic field, like extremely low temperature and ultra-high pressure, is listed as one of the most important extreme conditions in modern scientific experiments. Under these conditions, the properties of matter will be regulated, which will help scientists to discover new phenomena and explore new laws of matter. For example, in the study of biological macromolecules closely related to human health, many samples can only be liquid, so they can only be studied under strong magnetic fields.
