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.

A breakthrough moment in a physics experiment demonstrating the Faraday effect, showing how magnetic fields can influence the rotation of light polarization. This captures the key moment when the ...

If you’re a fan of science, and especially science history, no trip to London is complete without visiting the Royal Institution, browsing the extensive collection of artifacts housed in the Faraday ...
