This Faraday effect (FE) has been used since its discovery by [Michael Faraday] in 1845 for a wide range of applications, allowing for the manipulation of light’s polarization, something which is very useful in the field of optics, for remote sensing and spintronics. Despite this being such a well-known property of EM radiation a recent study <a href="https://www.nature.com/articles/s41598-025-24492-9" target="_blank">claims to have made</a> a new discovery here, with what they claim is about the ‘optical magnetic field’.</p>
<p>Their central claim is that it is not just the electrical component that contributes to the FE, but also the magnetic one, due to <a href="https://en.wikipedia.org/wiki/Zeeman_energy" target="_blank">Zeeman energy</a> that expresses itself from the magnetic component as a form of inverse FE. Based on their experimental findings they estimate that it contributes to the final measured FE by about 17% at a wavelength of 800 nm.</p>
<p>While definitely a very niche physics paper, and with no immediate implications, if independently confirmed it could deepen our understanding of t](https://files.mastodon.social/cache/media_attachments/files/115/852/010/542/005/090/original/5f69b849c0c9dfad.jpeg)
🚀🔍 Breaking news: Scientists finally find a hidden magnetic component in the Faraday effect after only 200 years of looking. 🎩🔍 Apparently, nobody noticed the giant "Do Not Disturb" sign on the lab door until now. 🙃 Better late than never, right?
