Magneto-optic effects refer to the changes in the optical properties of a material when it is subjected to a magnetic field. These effects can alter how light is absorbed, reflected, or transmitted through the material, often leading to phenomena such as Faraday rotation, where the plane of polarization of light rotates as it passes through a magnetized medium. These effects are utilized in various applications, including optical isolators and magnetic sensors. By leveraging the interaction between light and magnetism, scientists and engineers can develop advanced technologies for telecommunications, data storage, and imaging systems.
