In this study, COMSOL Multiphysics® software was applied to the investigation of the electromagnetic behavior of an optical crystal submitted to the magnetic field generated by electric current in a near positioned metallic conductor. Moreover, the influence of a ferromagnetic apparatus (magnetic concentrator) on the magnetic field acting upon the crystal was investigated. Three cases were evaluated: i) a system composed by the metallic conductor and the optical crystal only; ii) a system constituted by the metallic conductor, the optical crystal and the magnetic concentrator; and iii) a system composed by an arrange of three set of metallic conductor, optical crystal and magnetic concentrator separated by an arbitrary distance.
