Scientists blow up their lab after creating the most powerful magnet in history

With magnetic fields above 1000 Tesla, interesting possibilities open up. The movement of electrons out of the material environments in which they are normally found can be observed. So they can be studied in a whole new light and explore new types of electronic devices. This research also might be useful for those working on fusion power generation.

To achieve the record, the team used a technique known as electromagnetic flux compression (EMFC). The instrument, which generates a low-intensity magnetic field of 3.2 Tesla, was coupled to a row of capacitors that generate 3.2 megajoules, which is an enormous amount of energy.

This compresses the magnetic field to a tiny area extremely quickly. But, as the team predicted, it can’t be compressed for very long, which eventually creates a shock wave that destroys the instrument. They expected this to happen after about 700 tesla because that’s what it was built for. But, incredibly, it hit 1,200 before it exploded.
