New research shows that light’s magnetic field is far more influential than scientists once believed. The team found that this magnetic component significantly affects how light rotates as it passes ...

With today's data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism are related. A new study revealed that the magnetic component of light ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...

Lighthouse Pulsar X-ray polarimetry delivers a dual result: NASA's IXPE confirms the 2008 theory that high-energy particles ...
