Previously, the strongest magnet was created in the United States in 1999 at the National High Magnetic Field Laboratory.
Scientists from the Chinese Academy of Sciences, using a hybrid magnet, created a record-breaking stable magnetic field of 45.22 Tesla, which is tens of thousands of times stronger than an ordinary souvenir refrigerator magnet. This was reported by ScienceAlert.
In doing so, it broke the previous world record of 45 Tesla, set in 1999 by a hybrid magnet at the US National High Magnetic Field Laboratory.
It is noted that American and Chinese physicists have been working on creating hybrid magnets for some time. It is a magnet that uses two different methods to create a magnetic field: an outer superconducting ring and an inner resistive Bitter magnet. Using these two technologies, you can create the strongest stable magnetic field.
In 2016, Chinese scientists developed their own 40 Tesla magnet. Since then, they have been working hard to break the American record.
“To achieve the 45.22 Tesla result for a stable magnetic field, we changed the structure of the magnet and created new materials, as well as optimized the performance of the hybrid magnet,” said Guangli Kuang of the Chinese Academy of Sciences.
The SHMFF magnet, according to the team, represents a step forward for materials science.
“The hybrid magnet of the National Steady State High Magnetic Field Experiment Facility creates the highest permanent magnetic field in the world, which effectively improves the experimental conditions for scientists to conduct research in the field of materials science and will play an indispensable key role in the study of magnetic fields of various strengths,” the team wrote on the site. High magnetic field laboratories.
It was earlier reported that the Chinese technology company Xiaomi introduced a prototype humanoid robot CyberOne.
