### Bridging Courses

Although there are no mandatory prerequisites for this exam, students are strongly recommended to take it after Physics I.

### Learning Achievements (Dublin Descriptors)

Knowledge and understanding

At the end of this course, each student  will know the classic electromagnetism with particular attention to  static and dynamic electric and magnetic fields including electromagnetic waves.

Applying knowledge and understanding

Each student will be able  to apply the  theory of classic electromagnetism to problems with charges in  static and dynamic  electric and magnetic fields. He/she  will be able to solve circuit equations with both contnuous and alternating currents.

Making judgements

Each student will be able to apply his/her knowledge to  problems not previously  discussed during this course.

Communication skills

Each student is  more than recommended to ask questions during this course and to    participate to discussions in order  to improve  his/her ability to present his/her work

Learning skills

The student knowledges at the end of this course will make him/her  able to face new technical or practical problems on electric circuits in presence of electromagnetic fields.

### Teaching Material

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

### Supporting Activities

The teaching material and specific communications from the lecturer can be found, together with other supporting activities, inside the Moodle platform › blended.uniurb.it

### Teaching, Attendance, Course Books and Assessment

Teaching

Theory lectures and laboratory exercises, both face-to-face and on-line.

Attendance

Although recommended, course attendance is not mandatory.

Course books

Recommended books for theory and exercises:
Mazzoldi, Nigro, Voci, "Elementi di Fisica, Vol. 2 - Elettromagnetismo e Onde", EdiSES, 2008. [URL]
Halliday, Resnick, Krane, "Fisica 2", Casa Editrice Ambrosiana, 2004. [URL]

Recommended books for in depth-study exercises:
Bruno, D'Agostino, Santoro, "Esercizi di Fisica - Elettromagnetismo", Casa Editrice Ambrosiana, 2004. [URL]
Pavan, Sartori, "Problemi di Fisica 2 Risolti e Commentati", Casa Editrice Ambrosiana, 2006. [URL]

Assessment

Written and oral exams.

The written exam consists of three problems on different parts of the program. To each problem is assigned a maximum numerical value of ten, for a maximum of 30. The duration of the written test is two hours. It is passed if the mark (which remains valid one year) is not less than 18/30. In case of positive result of the written test, the oral exam (which can be taken only if the written exam is passed) consists of not less than three questions randomly extracted from the program. To each question is assigned a maximum numerical value of of 10, for a maximum of 30.  The oral test can be considered passed if the mark is 18/30 or more. The final mark is determined by the weighted mean of the marks of the written exam and the oral exam, with weights of 1/3 and 2/3, respectively.

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
