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 ...

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 ...

Researchers at the National High Magnetic Field Laboratory in Tallahassee, Florida, have pushed a palm-sized superconducting coil to 42 tesla, placing a device small enough to hold in one hand within ...
