**Abstract**

At the present, the development of life has led animals to have different behaviors in their evolutionary cycle, especially mice. For this reason, when mice are expose to physical agents such as electromagnetic fields, different behaviors can be found within their habitat and diet. Therefore, the analysis based on observation of the behavior of mice exposed to electromagnetic fields of different frequencies have been developed in the city of Potosí, Bolivia, which is located at an altitude of 3950 MASL. The methodology applied is the explanatory and longitudinal research. It is concluded that the influence of electromagnetic fields on the behavior of the mice generates a high stress index, influencing the change in the social behavior of the mice.
