The World’s Strongest Magnetic Field Went Out of Control And Blew Up Laboratory’s Doors


Last April, a team of researchers from the Institute of Solid State Physics at the University of Tokyo, in Japan, created the world’s strongest magnetic field. This sophisticated device, designed to examine semiconductors and other materials at a nanoscale, which for the first time surpassed 1,000 teslas in a controlled manner, is marking a new milestone for science, as stated in the study published in the Review of Scientific Instruments.

The world’s strongest magnetic field went out of control and blew up the Japanese lab’s door

To make this possible, the team led by Shojiro Takeyama applied energy of 3.2 megajoules on a sophisticated electromagnetic coil capable of compressing at a speed of Mach 15 (5 kilometers per second). As a result, the magnetic field created from this energy was able to squeeze into a shrinking space, thus increasing its intensity in a matter of microseconds.

However, after reaching 1,200 teslas of resistance, the coil was destroyed. The magnet, which had an iron casing designed to resist about 700 teslas (the unit that measures the intensity of the magnetic field), could not withstand the impact after reaching 1,200 units. As a result, the world’s strongest magnetic field went out of control and blew up the laboratory doors, as shown in a video published by the Institute of Electrical and Electronic Engineering.

“I did not expect such a big explosion. Next time I’ll make a stronger casing,” said Shojiro Takeyama.

The next phase is to create a controllable magnetic field of 1,500 teslas

Thanks to this new achievement, the researchers have been able to learn more about the movement of electrons out of the material environment in which they normally find themselves. This scientific milestone opens the possibility to explore new types of electronic devices and learn more about “fusion power generation.”

Takeyama and his team are now working to make the magnetic field measurement space a little larger, 10 millimetres. Thanks to this, the research team hopes to reach a controllable magnetic field of 1,500 teslas, marking a new scientific milestone.
