As stellarator configurations are challenging to build, most fusion experiments today are tokamaks (a short form for a Russian expression that translates as ‘toroidal chamber with magnetic coils’).

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

Gravitational wave detectors, such as LIGO, have revolutionized astronomy, but only within a narrow frequency range. Now, physicists have found a way to dramatically widen that range using something ...

In Hefei, China, physicists switched on a new machine that pushed magnetic fields to record strength. As the device powered up, it held a magnetic field more than 700,000 times stronger than Earth’s ...
