A nuclear fusion experiment at the University of Wisconsin-Madison has set a record for the strongest steady magnetic field confining a plasma, ushering in new hope that forthcoming demonstration ...

Winding a thin tape of superconducting material tightly enough can form a powerful magnet the size of a wristwatch. This could enable the creation of more sensitive nuclear magnetic resonance devices ...

Researchers have developed a new class of magnets that does not require rare earths and platinum, yet offers high magnetic ...

A team of international researchers led by the University of Ottawa has made a breakthrough in the development of ultra-thin magnets—a discovery that could lead to faster, more energy-efficient ...

A comprehensive study of high-temperature superconducting magnets confirms they meet requirements for an economic, compact fusion power plant. In the predawn hours of Sept. 5, 2021, engineers achieved ...

Earth’s magnetic field protects life from harmful cosmic radiation. But sometime between about 590 million and 565 million years ago, that security blanket seems to have been much thinner — with ...
