## goals

Students have a basic understanding of Maxwell's equations in integral form as well as of selected applications. They are able apply the equations to solve simple problems.

## content

Maxwell's equations in integral form and some applications:

• The electrostatic field: electric field strength; electric flux density; electric potential; the capacitance; energy and forces in electrical fields; material media in electrical fields
• The electrical current: current and current density; Ohm's law; electric flow field; energy conversion in electric circuits
• The stationary magnetic field: magnetic flux density; magnetic field strength; Lorentz force; Ampere’s Circuital Law; material media in magnetic fields; magnetic circuits; applications of magnetic forces
• The magnetic induction: induction due to motion within a magnetic field; induction due to a alternating magnetic field; inductance and mutual inductance; energy in magnetic fields; Eddy currents and Skin effect
• The transformer: the ideal transformer; nonideal transformer models; applications

## recommended knowledge

Students must have basic knowledge of differential and integral calculus and vector analysis as teached in senior classes of German Gymnasium. Also they should have basic knowledge about DC and AC Network Analysis using complex numbers as teached in the lecture „Fun­da­men­tals of Elec­tri­cal En­gi­nee­ring - Elec­tric Cir­cuits“.

## miscellaneous

Im Sommersemester 2021 wird dieser Kurs als online-gestützte Veranstaltung ohne Präsenzveranstaltungen durchgeführt. Die Koordination der Kursaktivitäten wird über Moodle erfolgen.
