Knowledge and understanding:
At the end of the course the student should have acquired the elements of classical electromagnetism and of the basic properties of dielectric and magnetic matter.

Applying knowledge and understanding:
The student at the end of the course should be able to apply the knowledge acquired to simple
problems of electromagnetism.

Making judgements:
The student at the end of the course should be able to recognize by himself the appropriate
Approximations to the calculation of relevant quantities in electromagnetism.

Communicating skills:
The student at the end of the course should be able to present orally the topics dealt with in the course using an appropriate science language and mathematical formalism.

Learning skills:
The main text book is Italian and it is complemented by chapter or articles in English. This will stimulate the learning skills and to go deep in complementary subjects to the main course.

Teaching methods

Lectures and excercises in the classroom For working students: possibility to follow the course on textbooks.

Assessment methods

The exam consists of a written test aimed at verifying the ability to solve electromagnetism problems and an oral test aimed at to verify the knowledge of the laws of electromagnetism and their theoretical and experimental implications and developments. The overall mark takes into account the results of both tests. Rehearsals could be conducted in the presence or remotely depending on the evolution of the COVID19 situation

Learning outcomes

Knowledge and understanding:
The learning of concepts and basic laws of electromagnetism must allow the student to describe phenomena related to electromagnetism through the concepts of source and field.

Applying knowledge and understanding:
The application of the fundamental laws of electromagnetism must bring the student to solve problems and interpret Experiences in a quantitative way.

Making judgments:
At the end of the course the student should be able to choose the most appropriate description of the problem of electromagnetism, by, for example, the use of the concepts of field or potential, the use of the symmetries of the problem, the laws of Maxell in full or local.

Communication skills:
The written test will allow the student to set a problem of electromagnetism in a rigorous and orderly. The test oralepermettera 'the student to develop the ability' to support a scientific discussion with appropriate language.

Learning skills:
At the end of the course students will have developed enough curiosity for the topics covered and the capacity to take on their own side of some aspects
proposed topics in the course.
