On Friday (August 12), the People’s Republic of China launched the most powerful magnet ever constructed on Earth with the intention of conducting scientific research in a laboratory.

The diameter of the magnetic field facility is 33 millimeters, making it only slightly larger than a coin.

The High Magnetic Field Laboratory of the Chinese Academy of Sciences, located in the city of Hefei, reports that it can generate a stable magnetic field with a strength of 45.22 tesla, which is more than a million times stronger than the magnetic core of the Earth.
