One such technique is based on the Faraday magnetooptic effect. The technique is nondestructive, relatively simple, and efficient, and beat lengths of 2 mm and less have been measured accurately with it, thus fulfilling the measurement requirements for many of the currently. The Faraday effect or Faraday rotation, sometimes referred to as the magneto-optic Faraday effect (MOFE), is a physical magneto-optical phenomenon. The Faraday effect can be observed in wide spectral regions from the ultraviolet to visible and infrared. on-garnet iYIGI sensing element and two flux concentrators are described. In the sensing head. The Faraday effect is the rotation of the polarization state of light when it passes through a magnetic field, B. This field could be induced by an electrical current.
