Current researches on Didactics of Physics have determined the importance about problematic in the teaching and learning process of scientific fundamental concepts in both high school and university levels. Such difficulties are analyzed through this work, especially in the area of the electromagnetism learning process with technology and university students. The research has a qualitative approach and a questionnaire was applied to 94 students in order to get suitable results. According to this, most of students (no matter how many times they had taken the course) have problems to understand the concepts related to the source of the magnetic field.
