  • Objectives

    Objectives

    Knowing and applying the Coulomb's and the Gauss's law to calculate the electric field caused by a set of point charges or charge distributions and analyze their behavior depending on the distance to the field source;  Understanding the concepts and physical meaning of divergence and rotational;  To apply the law of Biot-Savart and Ampere's law to determine magnetic fields caused by current flow in conductive materials;  Understanding the behavior of magnetic fields depending on the distance to the field source;  Understanding and applying the law of Faraday induction to the calculation of magnetic fields;  Understanding and applying the methodologies of analysis of magnetic circuits with different geometries;
  • Teaching methodologies

    Teaching methodologies

    The course is divided into theoretical and practical sessions. In the theoretical sessions, rather than using an expository method, the aim is to captivate and foster a spirit of intervention, constantly presenting theoretical needs for application development, which require a chain of reasoning without resorting to paper or programming, thus expanding the capacity for segmented reasoning. In the practical sessions, challenges will be presented that should generate optimized solutions. The assessment regime will include a final exam (65%) and a practical assignment (35%). A minimum grade of 7/20 is required in each assessment element.
