Scientists have created the world's most powerful superconducting magnet that can create a magnetic magnetic field intensity of 45.5 tesla. Only pulsed magnets that carry fields in a fraction of one second at a time have achieved higher intensities.
Materials Researcher David Larbalestier and his US National High Magnetic Field Laboratory (NHMFL) co-workers in Tallahassee, Florida, ran intense electrical currents through coils made of a coupled superconductor to generate low energy consumption magnetic fields. The resulting field strength exceeded that of energy-resistant resistive magnets ̵
Previously, cuprate-based magnets have been too fragile for use in technical applications, but the romance design should be able to maintain fields up to 60 tesla, Larbalestier says. Thousands of researchers take their examinations for magnetic installations such as NHMFL each year to conduct experiments with higher intensity fields than can be achieved in a typical laboratory.
