For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

Scientists have recently discovered an interaction between an electromagnetic wave and its own magnetic component as it passes through a material, updating a 180-year-old assumption that only ...

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 ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

High magnetic fields are a vital tool in many areas of science and technology that impact our everyday lives, from medical diagnostics through magnetic resonance imaging (MRI) to drug discovery ...
