- be able to use cylindrical coordinates, spherical coordinates, the nabla operator, Stokes´ theorem and Gauss´ theorem
- be able to use equations such as Coulomb's law, Biot-Savart's law, the law of induction and Maxwell's equations
- be able to explain concepts such as capacitance, inductance, induction, wave propagation and antenna

*Skills and abilities*

For a passing grade the student must

- be able to analyse an solve basic problems of electrostatics, magnetostatics, quasistationary and general electromagnetic field theory
- be able to explain how given problems of electromagnetic field theory can be solved

*Judgement and approach*

For a passing grade the student must

- understand that electromagnetic field theory is fundamental for all technique and all science that involves electric, magnetic and electromagnetic fields
- be able to describe the strength of and the possibilities of a mathematical model of the type that electromagnetic field theory is an example of
