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 ...

In a paper published January 21 in Nature, a team led by scientists at the University of Wisconsin–Madison have run complex numerical simulations of plasma flows that, while leading to turbulence, ...

Magnetic deposits laid down during the Ediacaran Period, 630 million years ago to 541 million years ago, are not inexplicable fluctuations, some researchers argue. Instead, there is a pattern encoded ...

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 ...

Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun's outermost layers. If confirmed, the findings could help scientists better predict space ...
