Researchers have created DNA-like magnetic nanostructures that form strong inter-helix magnetic bonds. These produce topological textures in the magnetic field, opening the door to the next generation ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale ...

Solve the falling wire problem to find terminal velocity in a magnetic field. See how motion through a magnetic field induces an emf and current, creating a magnetic force that opposes the fall ...

The sun’s surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed ...
