AIMS AND CONTENT

LEARNING OUTCOMES

The module is designed to provide to Students the knowledge and operational skills indispensable to properly describe, analyze and solve problems of static and quasi-stationary Electric and Magnetic Fields, introducing the models based on their integral formulation, with particular emphasis on Magnetic Circuits and the practical applications of electromagnetic induction.

AIMS AND LEARNING OUTCOMES

At the end of the module, the Student shall have correctly understood the basic concepts of low frequency Electromagnetic Theory, shall be able to correctly classify the different types of encountered problems, and to correctly formulate the solution, arriving, when possible, to determine their analytical solution.

TEACHING METHODS

Theory lectures and related exercises in the second semester (6 credits).

Students having disabilities or Specific Learning Disorders can request suitable aids for the examinations. Such aids will be defined according to specific needs, together with the Referent for the Polytechnic School of the Committe for the inclusion of Students with Disabilites and with SLD. Students in such conditions are invited to get in touch (via e-mail) with the Teacher a sufficient time before the examination, inserting in copy the Referent for the Polytechninc School (https://unige.it/en/commissioni/comitatoperlinclusionedeglistudenticondisabilita.html), without sending any document about their disabilites.

EXAMS

EXAM DESCRIPTION

The examination of Electric and Magnetic Fields is based on an oral discussion, lasting about 30 minutes, normally about the solution of practical problems, and optional questions about the related theory.

The final marking of Elettrotecnica is the average of the marks (rounded to the higher integer figure) of its modules (Electric Circuit and Electric and Magnetic Fields). The partial examinations must be passed in the following order: at first Electric Circuit, and afterwards Electric and Magnetic Fields.

ASSESSMENT METHODS

In oral exams are verified: the correct understanding of some theoretical subjects regarding all the content of the course, the correct use of technical language, the ability to critically examine the presented subjects and the successful learning of the technical competence necessary for the fruitful continuation of studies.
