Fusion researchers have long known that powerful magnets are the key to turning star-like reactions into a practical power source, and the latest generation of “super magnets” is starting to look less ...

Powerful "super-magnets" found in adult desk toys and other novelty items still trigger many emergency-room visits after children swallow them, according to a new report, even though some products ...

Magnesium diboride (MgB 2) is a low-cost, non-toxic superconductor used in field magnets, electric motors, and generators. However, producing nanoscale boron (B) particles to fabricate MgB 2 is ...
