Even at these low temperatures and high pressures, superconductors have found their way into a variety of world-changing technologies, mostly through superconducting wires that create powerful electromagnets. CERN’s Large Hadron Collider, the largest particle accelerator in the world, uses superconducting electromagnets to “bend and tighten” a particle’s trajectory; and the ITER tokamak, the most advanced fusion reactor on the planet, will contain the most integrated superconducting magnet system ever built when it goes online in 2025. But the most ubiquitous use of superconductors is in magnetic resonance imaging (MRI) machines, which leverage superconducting electromagnets to glimpse the human body in unprecedented detail.
