Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

A magnetic cloak works by diverting external magnetic fields so that, to an external observer, the object appears to be absent or invisible. Although this idea ...

A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general ...
