Contents
The specific program for each course is available on the personal page of the didactic portal. The specific programs can present small differences for the different areas (Industrial Engineering, Civil Engineering, Information Technology Engineering, Management Engineering), and can show different deepening, elaborations and applications of the same fundamental subjects which are common to all Physics II courses.


The Physics II course explains the fundamental laws of classical electromagnetism, including the propagation of light considered as an electromagnetic wave. The objective of the course is the acquisition of the basic principles and of their physical meanings. The fundamental applications of each law are shown with the aim of providing the student with a method for the interpretation of the physical phenomena which are at the basis of many engineering problems. A good knowledge and mastery of the mathematical instruments learnt in the course of Mathematical Analysis I and II and of Geometry are required. Electrostatics in vacuum is treated in the Physics I course and must be known at the beginning of the Physics II course. This knowledge is fundamental for the comprehension of all the subjects that will be studied.
