Orthogonal extinction method is a commonly used way for testing Faraday effect of magneto-optical materials.As accurate measurement of magnetic field intensity is difficult,the Finite Element Method (FEM) is used to study the influencing factor of magnetic field to improve the test solution.Compared to the traditional method,both accuracy and precision are enhanced.The method can be applied to measure the Verdet constant of magneto-optical materials.
