Contents	Electromagnetism. Maxwell's equations. Physical optics.
Reference texts	Any univeristary textbook for physics, mathematics and engineering courses is OK. A possible choice is the following: Mazzoldi-Nigro-Voci, Elementi di Fisica, Elettromagnetismo e Onde, EdiSes.
Educational objectives	Understanding the fundamental principles of electromagnetism. Applying these principles to the solution of problems of considerable practical relevance.
Prerequisites	It is necessary to know the contents of the courses of Analisi Matematica I, Geometria and Fisica A. It is also recommended to know the topics of Analisi Matematica II.
Teaching methods	Face-to-face lessons, including both thoery and problem-solving.
Learning verification modality	Written test lasting 2 hours is aimed at verifying the student's ability to solve exercises and/or problems in electromagnetism also with application references related to the specific course. There will be 3 exercises to be carried out and they will concern in particular the areas of electrostatics, circuits and magnetic phenomena. The choice of these 3 main areas is due to the importance of knowledge of the fundamental phenomena of electromagnetism and is aimed at verifying the student's problem solving ability and completeness of preparation. On the same or later date (at the student's choice), a second written test, lasting one hour, will follow, during which general questions on the various parts of the program will be proposed to be answered in open form. This second test serves as an oral equivalent and is designed to test the student's ability to expound clearly, concisely and comprehensively on the course topics.
