    OVERVIEW

    Module of static and low frequency Electric and Magnetic Fields

    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).

    EXAMS

    EXAM DESCRIPTION

    Oral only.

    ASSESSMENT METHODS

    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.
