Decisions and guidelines

Required: Vector calculus (Gauss's and Stokes' laws) from Geometry and Calculus III, which preferably are studied in parallel with the first half of the course.

Learning outcomes

On completion of the course, the student should be able to:

  • make mathematical models of a given electromagnetic system
  • perform calculations of electric and magnetic fields for selected geometries and boundary conditions
  • derive, explain and calculate static and time dependent currents in circuits containing resistors, capacitors and inductors
  • give examples of and explain electromagnetic phenomena and electric circuits, as well as working principles of simple electrical devices
  • give an account of how electromagnetic waves transport energy in space
  • plan and perform measurements on electromagnetic circuits with the most common measurement instruments

Instruction

Lectures, exercises and laboratory exercises. Exercise sessions with problem solving in smaller groups may occur, as well as exercises in computer halls. Subject-integrated communications training, including feedback and self-evaluation, are included in the course.

Assessment

Mandatory home assignments (2 credits)
Written exam (6 credits)
Laboratory exercises (2 credits)

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
