Aim:
The overall goal is that the student - with the Maxwell equations, MW, as starting point, should be able to define, derive and use basic electromagnetic laws and theorems on problems in physics and electrical engineering. This implies that the student should:
- be familiar with and able to use electromagnetic laws and theorems
- be able to formulate idealized models for electromagnetic problems
- be able to apply electromagnetic theory to solve problems primarily in physics and electrical engineering
- be able to explain in a well structured and logical concise way derivations/relations within electromagnetics as well as between the central concepts of the theory
- be able to formulate, analyze and solve electrostatic problems with the help of a modern numeric computer tool
- be able to use electromagnetic theory to qualitatively explain in a well structured and logical concise way numerically obtained results

Course contents:
Electrostatics: Electric Field Intensity, Coulomb's law, Potential, Gauss's law, Poisson's and Laplace's Equations, Capacitance, Dielectrics, Electric Dipole, Polarization, Electrostatic Energy and Forces, Method of Images. Steady Electric Currents: Current Density, Equation of Continuity, Resistance, Joule's law. Magnetostatics: Magnetic Flux Density, Biot-Savart law, Ampere's Circuital law, Vector Magnetic Potential, Magnetic Materials, Magnetic Circuits, Magnetic Dipole, Magnetization, Magnetostatic Energy and Forces, Motion of Charged Particles in Electromagnetic Fields. Time-Varying Electromagnetic Fields: Induction, Faraday's law, Inductance, Electromotive Force, Displacement Current Density, Skin Effect, Electromagnetic Waves, Poynting Vector. Snell's laws of reflection and refraction, and Fresnel's formulas are derived from electromagnetics. Certain applications of electromagnetics on waveguides. The finite-elemet-method in two dimensions will be briefly introduced for electrostatic problems. The different parts of the course are presented as specific applications of Maxwell's equations.
