In this course will be acquired competences on the understanding of Nature in the domain of the Electromagnetic phenomena, emphasizing the most technologically more important concepts. The theoretical studies are complemented with laboratory work.


It is developed the knowledge and ability to understand the field of electromagnetism, leaning on the high-school level of expertise and on adequate and updated texts of international authors. The knowledge acquired is promoted by conducting theoretical and practical exercises and applied in the laboratories, which develop a professional attitude towards work. The student is compelled to engage in situations of a practical nature (laboratories) or theoretical-practical (written examinations) where he should carry out judgments and decisions. The subjects taught are largely basic concepts of scientific and technical literacy, relevant to a broad understanding of nature and applications, and in the communication of ideas with scientific basis. The laboratory group work allows exercising interpersonal exchanges of ideas and discussion of problems and solutions. The individual study of the subjects taught, supported by tutorial contacts, forms an important part of the work plan, acquiring the students habits of autonomous acquisition of knowledge.
