Every once in a while, we all need a good reminder that electromagnetism is mind-boggling. Thankfully, in its latest video, the YouTube channel The Action Lab offers a stellar nod to the force of ...

Mr. Cote is an engineering physicist who has worked with superconductors in condensed matter physics labs and particle accelerators and has designed superconducting magnet systems for nuclear fusion.

Superconductivity is a fascinating phenomenon in which certain materials exhibit zero electrical resistance and expel magnetic fields below a characteristic temperature, known as the critical ...

The video is subtle. A small, regular chip of stonelike material as wide as the end of a ballpoint pen rests on a flat metal surface. But it’s not resting, exactly: While one end touches the metal, ...

Some researchers in Korea have made an extraordinary claim that they’ve developed a superconductor that works at room temperature and pressure. It’s getting a lot of attention — and skepticism. A room ...
