• scalarpotential; electrostatic energy; leader; capacitance
• method of images
• electric dipole; polarization; bound charges; D field; dielectrics; permittivity
• current density; conductivity; resistance; Joule's law
• Biot-Savart law, magnetic field B; continuity equation; Ampere's law; vector potential
• magnetic dipole; magnetization; bound current densities; H-field; permeability
• electromotive force; induction; inductance; magnetic energy

General goals

After the course the student shall from a description of a situation that leads to an electromagnetic field problems be able to

• use their conceptual understanding of the electromagnetic laws in order to qualitatively describe the behavior of the solution to the problem
• use their ability to manage the electromagnetic laws to, in simple situations, set up a computational model and perform the necessary calculations: select appropriate methods; make appropriate approximations; plausibility assess the results

Concrete goals

1. define electric and magnetic fields according to their force effect
2. explain the physical meanings of the differential equations for electrostatic and magnetostatic fields
3. calculate the electric field from the stationary charge distributions and magnetic fields from steady current distributions
4. solve simple electrostatic boundary value problems
5. describe and use simple models of electric and magnetic field interactions with materials
6. explain the concept of electromotive force

Corresponding to the courses for the Degree Program in Energy and Environment (CENMI) in

• Linear algebra
• Differential and integral calculus, in one and several variables
• Electrical circuit analysis
• Vector analysis

Through knowledge of 1:st year courses in mathematics (up to and including Guass and Stokes theorems for vector quantities) and science (basic concepts like force, power, energy, center of gravity). 

If the course is discontinued, students may request to be examined during the following two academic years.

• TEN1 - Written Exam, 6.0 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Passed in all examination moments.

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
