AIMS AND CONTENT

AIMS AND LEARNING OUTCOMES

The target of the module is to provide basic notions of electromagnetism and to enable students to understand and be able to evaluate the electromagnetic aspects that determine the behaviour the simplest electrical components and circuits.
At the end of the course, the students will be able to:
1. explain the most important phenomena of electrostatics and magnetostatics
2. explain the fundamental concepts underlying the operation of electrical components
3. solve simple problems of electrostatics and magnetostatics
4. solve simple problems concerning the operation of electrical components

TEACHING METHODS

Lessons and exercises are carried out in the classroom by the teacher.

SYLLABUS/CONTENT

This module, dealing with topics of scientific-technological interest such as basic electromagnetic fields, contributes to the achievement of the following Sustainable Development Goals of the UN 2030 Agenda:
8.2 (Achieving higher standards of economic productivity through diversification, technological progress and innovation, also with particular attention to high added value and labor intensive sectors)
9.5 (Increase scientific research, improve the technological capabilities of the industrial sector in all states - especially in developing countries - as well as encourage innovations and substantially increase, by 2030, the number of employees for every million people, in the research and development sector and expenditure on research – both public and private – and on development)

EXAMS

EXAM DESCRIPTION

The exam is oral and consists of two questions, for a total duration of half an hour. One of the questions will be theoretical and one will be focused on the resolution of an exercise.

ASSESSMENT METHODS

The theoretical question will allow to evaluate the ability to explain the most relevant aspects of electrostatics and magnetostatics or the fundamental concepts that underlie the operation of the most important electrical components. The exercise will allow to evaluate the ability to solve simple problems in the same contexts.
