Entry requirements

Algebra and Geometry, Single Variable Calculus, Scientific Computing I/Computer programming I, Mechanics Basic Course (force, energy, particle motion). Knowledge of line and surface integrals from the course Several Variable Calculus is needed. This course can be studied simultaneously with Electromagnetism I.

Learning outcomes

Electromagnetism is a fundamental part of classical physics with considerable technological applications. The course constitutes a basis for further studies in physics, electrical engineering and materials science.

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

• performing calculations of electric and magnetic fields in space in some selected geometries with boundary conditions.
• performing calculations of stationary and time-dependent electrical currents in selected circuits containing resistors, capacitors, and inductors.
• accounting for the operational principles of common electrical devices.
• handling the most common instruments for electrical measurements.
• account for basic theories in electrostatics, electrical circuits, stationary electromagnetism and electromagnetic induction,

Instruction

Assessment

Laboratory exercises (1 credit)

Written examination at the end of the course (4 credits) and a non-compulsory half-time examination. Passing the half-time examination will give the student a bonus which is only valid at the final examination at the end of the course and at the first scheduled re-examination.

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.
