These advancements could pave the way for researchers to uncover unexpected new physics.<\/p>\n<p>High-field magnets are essential tools for exploring the hidden properties of advanced materials like superconductors, which can carry electric current without generating waste heat at very low temperatures. These powerful magnetic fields also provide opportunities to observe entirely new physical phenomena and manipulate states of matter, offering valuable insights into condensed-matter physics.<\/p>\n<\/div>\n<\/div>\n<div>\n<div>\n<p>According to Alexander Eaton, a condensed-matter physicist at the University of Cambridge, high magnetic fields are especially useful for experiments requiring highly sensitive measurements, as they enhance resolution and make detecting subtle phenomena easier.\u00a0<\/p>\n<p>Each additional tesla greatly improves the precision of these measurements, enabling clearer insights into elusive physical effects.<\/p>\n<p>Guangli Kuang, a high magnetic field specialist at SHMFF (Chinese Academy of Sciences\u2019s Steady High Magnetic Field Facility), explained that the team dedicated years to refining the magnet to reach this new record, noting that the achievement was far from easy.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-new-study-highlights-advantages-of-resistive-magnets\">New study highlights advantages of resistive magnets<\/h2>\n<p>Resistive magnets, though older technology, can maintain high magnetic fields for longer durations compared to newer hybrid or fully superconducting magnets. They also offer the advantage of quickly ramping up their magnetic fields, making them highly versatile for experiments.\u00a0<\/p>\n<\/div>\n<\/div>\n<div>\n<div>\n<p>However, their major drawback is the significant power consumption, which makes them costly to operate. For instance, the SHMFF\u2019s resistive magnet required 32.3 megawatts of electricity to achieve its record-breaking field, necessitating a strong scientific justification for such resource use.<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<p>\n<iframe loading=\"lazy\" title=\"Unbelievable Technology: See the Magic Behind Maglev Trains\" width=\"1170\" height=\"658\" src=\"https:\/\/www.youtube.com\/embed\/8os4A4li674?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/p>\n<\/figure>\n<p>The challenge of high power consumption is spurring the development of hybrid and fully superconducting magnets that can produce high magnetic fields with less energy.
