American scientists have produced the world's most powerful superconducting magnet, which can generate a record magnetic field strength of 45.5 Tesla, which exceeds the strength of traditional superconducting magnets and the most advanced impedance magnets, and can only sustain a few times A fraction of a second of a pulsed magnet can reach a higher magnetic field strength than this.
David Labalestiel, a materials scientist at the National High Magnetic Field Laboratory, and colleagues used coils made of copper salt superconductors to run a strong current to generate a low-energy magnetic field. The resulting magnetic field strength exceeds the state-of-the-art Impedance type magnet used in the magnet laboratory. Impedance type magnets do not use superconductors and have high energy consumption. In addition, the new magnets also surpass the strength of traditional superconducting magnets and "hybrid" superconducting-impedance magnets. The findings were published in the journal Nature on the 12th.
Rabalestiel said that previous copperate magnets were too fragile to be used in the technical field, but the latest design should be expected to maintain a magnetic field of up to 60 Tesla, which can be used in many research fields.
