Learning goals
Deepening of the knowledge in an essential field of Physics: electromagnetism. Ability to search and use bibliography, organizing a consistent amount of information regarding the mentioned field. Ability to solve problems, including the development of mathematical competences appropriate for this purpose. Ability to implement and interpret the simple experiments concerning the contents of the curricular unit. Contribution to the growth of general culture regarding Physics; motivating for the study of other fields related to electromagnetism and, especially, for the knowledge of multiple applications of electromagnetism to modern societies. Syllabus

Apontamentos do MIT, http://web.mit.edu/8.02t/www/, Liao et al. Teaching method
Classes for presentation of the essential concepts with the reflection on the way these concepts were established. Classes for discussion/resolution of problems in which the approached concepts will be linked to practical situations, orders of magnitude, estimates on the physical quantities that are specific of electromagnetism field. Laboratory classes in which small experiments will be carried out to illustrate some essential concepts of electromagnetism. Support to students’ individual work so that they can develop a work of information collection, analysis of that information and elaboration of their own notes on the subjects approached in this curricular unit.
