Syllabus
Prerequisites: Knowledge of fundamentals of mechanics and thermodynamics are requested together with basics of differential and integral calculus.
Target skills and knowledge: Methodology in the description of fundamental phenomena in classical electromagnetism.
Examination methods: Written exam with essay questions and oral examination on the topics discussed during lectures.
Assessment criteria: In the written exam students are requested to set up and solve analitically and numerically simple problems describing physical situations regarding basical phenomena of electromagnetism and optics. In the oral exam students will describe and discuss about fundamental phenomena and the connections among them.
Course unit contents: This course introduces classical electromagnetism. Beginning from electrostatic phenomena between elementary charges, the course describes macroscopic phenomena of charge distributions. Properties of conducting materials and insulators and phenomena of electric conduction in resistive circuits are presented. The effect of magnetic field on charges and currents and the sources of magnetic field are described. Through the description of time dependent electromagnetic phenomena Maxwell equations are obtained. The course continues with the description of wave phenomena and in particular with electromagnetic waves. Wave propagation, interference ad diffraction phenomena are described in various aspects. A short introduction to basic electrodynamics is presented.
