Magnets, How Do They Work?

Scientists Debut Magnet Powerful Enough to Lift an Aircraft Carrier

Here’s what it looks like (so far).

Massive Magnets

Scientists in France have finally received one of their latest and most impressive tools in the effort to create nuclear fusion: a really big honkin’ magnet

Researchers at the International Thermonuclear Experimental Reactor (ITER) debuted the first part of the magnet on Thursday when they received it from its American manufacturer, according to The Associated Press. When fully assembled, the magnet stands at a staggering 60 feet tall and is 14 feet in diameter; it’s also powerful enough to lift an aircraft carrier. 

First-of-a-Kind

The magnet itself is actually known as a “central solenoid.” It’ll be used as a superconductor to attain the incredible amounts of heat and pressure necessary to produce nuclear fusion. The solenoid can generate a magnetic field roughly 280,000 times stronger than Earth’s magnetic field, according to New Scientist.

“Each completion of a major first-of-a-kind component — such as the central solenoid’s first module — increases our confidence that we can complete the complex engineering of the full machine,” said Laban Coblentz, spokesperson for ITER. 

Sun on Earth

Nuclear fusion has been something of an El Dorado for many scientists over the years. Though it promises clean energy that’ll cut down greenhouse gas emissions, it is incredibly difficult to achieve, and scientists have yet to produce a reactor that produces more energy than it consumes. 

However, the ITER fusion reactor is slated to be one of the largest reactors out there and many believe it’s one of the more promising efforts to finally achieve the elusive goal of nuclear fusion.
