Physics does not yet know why copper-based superconductors (cuprates) conduct electrical current without dissipation at unprecedentedly high temperatures. Ultra high magnetic fields are used here to suppress superconductivity in a cuprate near absolute zero temperature, revealing an underlying transition to an electronic phase that might be the cause of the superconductivity.

The coils have a limited life expectancy and thus need to be replaced on occasion. Fabrication of these large coils are now being done at the MagLab where advanced nondestructive examinations can be performed. Because of more rigorous quality controls and improvements in high-strength conductors and reinforcement materials, the lifetime of these coils can be extended.

Recent measurements of superconducting tapes in the MagLab's 45-tesla hybrid magnet shows that the power function dependence of current on magnetic field remains valid up to 45T in liquid helium, while for magnetic field in the plane of the tape conductor, almost no magnetic field dependence is observed. Thus design of ultra-high-field magnets capable of reaching 50T and higher is feasible using the latest high-critical current density REBCO tape.
