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 ...

The Muon g-2 collaboration has announced their much-anticipated updated measurement. The new result aligns with the collaboration's first result, announced in 2021—and it's twice as precise. In fact, ...

A trio of physicists, two with Coventry University, in the U.K., and the third with Laboratoire National des Champs Magnétiques Intenses, in France, has demonstrated how Earth's magnetic field may be ...

A team of physicists and engineers at Princeton Plasma Physics Laboratory built a twisting fusion reactor known as a stellarator that uses permanent magnets, showcasing a potentially cost-effective ...

The Action Lab explores whether two magnets can orbit each other in this simple physics experiment. Americans were asked where they’d move if they left the US.—here’s what they said. Would you choose ...

A nuclear fusion reaction has overcome two key barriers to operating in a “sweet spot” needed for optimal power production: boosting the plasma density and keeping that denser plasma contained. The ...

Commonwealth Fusion Systems has delivered two high-tech superconducting magnets to a University of Wisconsin experiment on magnetic mirror fusion technology. The magnets are the first products shipped ...

Physicists now have a brand-new measurement of a property of the muon called the anomalous magnetic moment that improves the precision of their previous result by a factor of 2. An international ...
