 Understand the basic effects that determine the behaviour of dielectric and magnetic materials when they are placed in electric and magnetic fields and are able to quantify the associated displacement and induction fields and the associated bound charge and currents,
 Oversee the conservation laws for energy and charge and contain the origin and simple properties of electromagnetic waves.



This course teaches the physics of the electric and magnetic phenomena and the phenomena that interconnect these. The course describes the phenomena initially separately, by recalling the empirical laws of Coulomb, BiotSvart, Ampere, and of induction. Next, these laws are expressed in terms of Vector calculus. Line, surface and volume integrals are applied to better reveal the physics behind these phenomena and to reveal the properties and spatial structure of the associated scalar and vector fields.
The course begins with Coulomb’s law, introduces Gauss’ law (differential and integral), and the electrostatic potential (differential and integral) and field energy. The properties of metals and dielectrics in electric fields, the polarization and the dielectric displacement fields are introduced after multipole expansion of the Coulomb potential. The magnetostatic phenomena are introduced in analogy, starting with BiotSavart’s law and the Lorentzforce, followed by Ampere’s law (differential and integral) and the magnetic vectorpotential (differential and integral). After introduction of the magnetic properties of matter (magnetization and magnetic induction fields), the connection between electric and magnetic phenomena is drawn in a first step via Ohm’s law, and then electrodynamics is introduced via the two laws of mutual induction (both in integral and differential form). The four obtained Maxwellequations are analyzed with their constitutional equations, to derive the existence of electromagnetic waves and some basic properties.
The course is partly consisting of lectures to provide an overview, guidance and general understanding. In the other part, homework questions are discussed in smaller groups, and solutions are presented and explained during seminars.

 Coulomb’s law, line, surface and volume charge distributions,
