MAGNETO OPTIC EFFECT

Any one of a number of phenomena in which an electromagnetic wave interacts with a magnetic field , or with matter under the influence of a magnetic field. ( 188 ) Note: The most important magneto-optic effect having application to optical communication is the Faraday effect , in which the plane of polarization is rotated under the influence of a magnetic field parallel to the direction of propagation . This effect may be used to modulate a lightwave.
