## Intended learning outcomes

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

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

## Course main content

- Coulomb's law; electric field E; charge distributions; Gauss' law
