Faraday Effect

The Faraday Effect refers to the phenomenon where the polarization of light changes when it passes through a magnetic field. When light travels through a material that is under the influence of a magnetic field, its plane of polarization rotates. This effect is named after the scientist Michael Faraday, who discovered it in the 19th century. The Faraday Effect has practical applications, including in optical isolators used in lasers, which prevent light from reflecting back into the source and protect the equipment from damage. It illustrates the interplay between light and magnetism in physics.
