The Verdet constant is a measure of the strength of the optical rotation of a material in response to an applied magnetic field. Specifically, it quantifies the angle of rotation of the polarization plane of light as it passes through a material in the presence of a magnetic field. This phenomenon is known as the Faraday effect, which is observed in certain materials, especially in glasses and crystals that possess a non-reciprocal optical response due to their magneto-optical properties.
