TWO CENTURIES ago Hans Christian Oersted, a Danish physicist, demonstrated that the motion of an electric charge produces magnetism. This was the first observation of a wide-ranging phenomenon. The ...

Small in-plane magnetic fields switch skyrmion chirality and improve lattice order in a two-dimensional magnet, pointing to ...

A new laser and microtube method lets scientists make huge magnetic fields for research. Previous lab-made magnetic fields were piddly and unimpressive, through no one's fault. These powerful magnetic ...

Scientists have created magnetized-plasma conditions similar to those near a black hole using very intense laser pulses. This work may help show how X-rays can be produced by astronomical objects.
