Story summary

Researchers at Hebrew University of Jerusalem update the Faraday effect, showing light's magnetic field influences matter.
They find the magnetic field accounts for 17% of the Faraday effect in visible light and 70% in infrared.
The findings reveal an interaction between light and electron spin, challenging the view that the electric field affects polarization.
The results point to advances in quantum computing and spintronics, urging reassessment of electromagnetic models.
