Objectives
In this discipline electric and magnetic static fields, as well as their temporal variations are studied, whose phenomenology is summarized in the physical-mathematical formalism of Maxwell''''''''''''''''''''''''''''''''s equations. These equations will be studied in both differential and integral formalisms, and several applications to concrete engineering situations are illustrated.
The goal of this course is to teach thinking skills, qualitative and mathematically, that can be applied in different circumstances to the every day life and to enhance collaborative problem solving skills.
