Magnetic Field Reaches 75 T

A major breakthrough has been made on the testing of a high-field magnet on Oct 26. The magnet designed, coiled and processed by Wuhan National High Magnetic Field Center achieves its 75 T that breaks the national record and is completed 2 years ahead of schedule.

In early 2010, the Center put the field strength of 75T as the focus of the work. The magnet with 10mm aperture and 100mm height is made of copper superconducting wire by 2x5mm and high strength HM Zylon fibre. This could be the world's highest-field magnet made of looped soft copper.

Through several months' efforts, 75 T is generated under the electric voltage of 20 KV. The peak current reaches 35.5KA. This success has accumulated experiences for the goal of a world renowned pulsed magnetic field center.
