This paper presents an educational experience in which we use the Learning Object (LO) "Cargo movements in a Magnetic Field" during the study of concepts related to the Lorentz force in a class of third year of High School in a public school in the state of São Paulo. Throughout this experience, we investigated the possible contributions of the LO for teaching concepts of Electromagnetism, from the development of investigative activities that contemplate the use of such an object. The study was guided by the qualitative paradigm and the analysis of the results showed that the simulations provided by LO allowed the visualization of the studied physical phenomena which, in the case of Electromagnetism, requires greater capacity for abstraction to be understood. The activities also favored the development of certain skills related to the competence of researching and understanding of the physical concepts. In addition, greater interaction among students and between students and the teacher was observed during classes where this research was developed.
