Educational objectives
The course aims to provide students with the basis for understanding all the fundamental processes of classical electrodynamics
To have acquired the concepts taught in the courses of Analysis 1 and 2 and Physics 1
Teaching methods
The course is essentially divided into 4 topics: Electrostatics, Magnetostatics, Classical Electrodynamics and Optics. Each topic will be addressed through lectures during which the theoretical bases of each topic will be presented, accompanied by examples and exercises.
Learning verification modality
The exam includes a written test and an oral exam. During the year 2 written intermediate evaluation tests could be proposed (exemptions).
