Aim

• The student shall acquire fundamental knowledge of vector analysis and electromagnetic theory

• The student shall acquire a good ability to perform calculations on given problems

• The student shall acquire good knowledge of the electromagnetic concepts that are used in electrotechnical applications, e.g., electronics, measurement techniques and electric power technique

Knowledge and understanding
For a passing grade the student must

• be able to explain how electric charge and electric current generate and are affected by electric and magnetic fields

• 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 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
