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 ...

Today bulky and expensive superconducting magnets are used to generate the strong magnetic fields (about seven tesla) needed for precision NMR (nuclear magnetic resonance). While portable magnets have ...

If you drop strong magnets onto a plate of copper, something remarkable happens: the magnets slow down before hitting the surface and appear to levitate slightly, like the copper is another magnet, ...
