Physicists Just Showed the Faraday Effect Works in a Totally New Way After Nearly 200 Years
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.
Nearly two centuries after Michael Faraday first showed that magnetism can twist light, physicists have gone back to that classic experiment and found a hidden piece of the puzzle. By teasing out a ...
