In the Faraday magneto-optic effect, when linearly polarized light passes through a Faraday magneto-optic crystal in the direction of the magnetic field, its polarization rotates, and the rotation angle is related to the strength of electromagnetic field. Therefore, the strength of magnetic field can be detected by utilizing the rotation angle. what more, if the magnetic field is generated by a current flowing through the target conductor, Faraday magneto-optic effect can be used to measure the current.
