In 1845, Michael Faraday showed that light and magnetism are linked. He passed a beam through glass inside a magnetic field and found that its polarization — the direction its waves wiggle — rotated.

Researchers at the Hebrew University of Jerusalem discovered that the magnetic component of light plays a direct role in the Faraday effect, overturning a 180-year-old assumption that only its ...

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 ...
