Teaching method
Conventional lectures with constant references to physical systems whose description might grab the attention of the students. We emphasize everyday situations that can be explained using the physical concepts included in the syllabus. In this way we try to illustrate the usefulness and the importance of the electromagnetism as a stuctural discipline in scientific and thechnological courses.
Resources used
