Entry requirements

Algebra and Geometry, Single Variable Calculus, Scientific Computing I (MATLAB), 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. Measuring Techniques or Electrical Measuring Techniques is strongly recommended.

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.

After passing the course, the student will be able to

• account for basic theories in electrostatics, electrical circuits, stationary electromagnetism and electromagnetic induction,
• 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.

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.
