Georgetown University researchers have discovered a new class of strong magnets that do not rely on rare-earth or precious metals—a breakthrough that could significantly advance clean energy ...

But powerful magnets are usually large and energy hungry. Chukun Gao at the Swiss Federal Institute of Technology in Zurich ...

A magnet small enough to fit in the palm of your hand can match the strength of some of the world’s most powerful magnets for the first time. But superconducting magnets that produce strong magnetic ...
