| contents | We investigate learning difficulties among second-year students on electromagnetism courses when they apply Ampère-Maxwell's law. Using phenomenography, we analysed written answers from 65 undergraduate physics students to four questions on Ampère's and Ampère-Maxwell's laws. We complemented our research by interviewing twelve students. To design the questionnaire, we ran an epistemological analysis of classical electromagnetism which helped us to identify a set of key essential concepts to understand this theory and guided the definition of learning objectives and to draw up the questions. The results revealed that the students found it hard to recognise the validity framework from Ampère's law and to apply Ampère-Maxwell's law. They face particular difficulties to recognise the appearance of the displacement current and the relationship between the circulation of the magnetic field and an electric field that is variable over time. |
