The world’s most powerful magnet is being sent to France to be used in the core of the experimenter fusion reactor ITER. Scientists hope that ITER will provide the power to create fusion energy on an industrial scale by replicating the process observed at the center of our Sun. This magnet is known as the central solenoid. The strength of this artificial magnet is 280,000 times greater than the Earth’s magnetic field.
280000 times stronger than Earth’s magnetic field
The central solenoid magnet is being divided into several parts and sent to France. When all the parts are connected, this magnet will be 18 meters long and 4.2 meters wide. Once fully built it will weigh around 1000 tonnes. The magnetic field strength of this magnet is around 13 Tesla, which would be about 280,000 times stronger than Earth’s own magnetic field.
Combination of six modules
To generate such a strong magnetic field, the part of the reactor in which the central solenoid will be installed must withstand a force equal to twice the thrust of the Space Shuttle lift-off. This magnet is made up of six modules. Each module contains 43 kilometers of coiled niobium-tin superconductors. Once these coils are installed, they will be sealed with 3800 liters of epoxy.
Weapons manufacturer made super powerful magnet
This magnet has been manufactured by America’s famous arms manufacturer General Atomics. The same company has manufactured many deadly drones and other war weapons like the MQ-9 Predator. Special preparations have been made to send this super-powerful magnet made at the General Atomics factory in California to the ITER manufacturing site in France. Its first module will leave this month, while the next module will be sent in August.
75% work of ITER completed
ITER scientists aim to activate the world’s largest fusion reactor by 2025. Scientists from 35 countries of the world including India are working in this project. 75% construction work of ITER has been completed. Through this nuclear fusion is to create energy on Earth. This will also give us special information about the origin of stars.
