Faraday rotation

Faraday rotation is a phenomenon that occurs when polarized light passes through a magnetic field in a material. As the light travels, its orientation rotates due to the interaction between the light waves and the magnetic field. This effect is utilized in various applications, such as in devices for measuring magnetic fields and in telecommunications to enhance signal clarity. Essentially, Faraday rotation helps scientists and engineers understand magnetic environments by observing how light behaves when influenced by magnetic forces.
