Electrical, optical and magnetic materials

A Magnetic material is unique of a quantity of phenomena in which an electromagnetic wave propagates through a medium that has been altered by the occurrence of a quasistatic magnetic field. In such a material, which is too called gyro tropic or gyromagnetic, left- and right-rotating elliptical polarizations can propagate at different speeds, leading to a number of important phenomena. Once light is conveyed a layer of magneto-optic material, the consequence is called the Faraday Effect: the plane of polarization can be rotated, forming a Faraday rotator. The results of reflection from a magneto-optic material are identified as the magneto-optic Kerr effect (not to be confused with the nonlinear Kerr effect).
