Researchers Create A Magnet That Is A Million Times Stronger Than Earth’s Magnetic Core

This 45.22-tesla magnet sits just shy of the world record for the earth’s most powerful magnet.



China apparently built the world’s most powerful magnet for scientific research at a lab in the south east town of Hefei, which is in the Anhui province, a statement by the South China Morning Post reports.

This magnet is said to be approximately the size of a coin, with a diameter of just thirty-three millimetres. Regardless of its small size, it makes a consistent magnetic field strength of 45.22 tesla, which is in excess of a million times greater than the Earth’s magnetic field.

World Record Setting Magnets

Researchers from the United States National High Magnetic Field Laboratory produced a world record-breaking 45.5-tesla field in 2019. That being said, these professionals did that just with a test magnet that wasn’t chosen in experiments.

The Hefei center has now become the best steady-state magnetic field that can assist scientific research.

The first record was made by the National High Magnetic Field Laboratory in the United States in 1999. Its hybrid magnet developed 450,000 gauss [45 tesla], and it has held the record for 23 years.

Producing such powerful magnetic fields necessitates an incredible mass of energy, though the rewards might also be world-changing. Scientists all over the world are creating astonishingly powerful magnets in a bid to harness the great capacity of nuclear fusion energy, which could decrease the whole world’s dependence on nonrenewable fuel sources.

At the Heifei facility, a team of scientists made use of a powerful magnet back in the year 2016 to perform experiments, which led to the observation of an all new physical phenomenon in carbon nanotubes. Their discovery has potential possibilities in the semiconductor market, as scientists are attempting to replace silicon with carbon in chips to make super-fast low-power computer systems.

Uncovering nuclear fusion as well as other advancements

Prof Kuang Guangli, the top scientist working on this project revealed that his team has successfully developed the most powerful magnet all over the world for scientific research purposes.

While the country’s magnetic field research laboratory started fairly late, it merely took approximately 10 years to make the big jump from zero to an innovator, creating the China speed for the innovation of strong magnetic modern technology the report concluded.
