It describes how an electric current produces a magnetic field and, conversely, how a changing magnetic field generates an electric current. When you purchase through links on our site, we may earn an ...
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 ...

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.
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 ...
