CODE 57194 ACADEMIC YEAR 2020/2021 CREDITS 8 cfu anno 2 SCIENZA DEI MATERIALI 8765 (L-30) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR FIS/01 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 1° Semester MODULES Questo insegnamento è un modulo di: GENERAL PHYSICS TEACHING MATERIALS AULAWEB AIMS AND CONTENT AIMS AND LEARNING OUTCOMES Understanding of the basic concepts of electromagnetism in vacuum. At the end of the first module, the student will be able to i) understand the origin of electric and magnetic fields and know their properties; ii) solve simple exercises on DC circuits; iii) extend the concepts of mechanics to situations involving electromagnetic forces and energies; iv) understand the mechanisms of electromagnetic induction; v) describe the properties of a plane electromagnetic wave. TEACHING METHODS Traditional lectures; exercises solved by the lecturer with the student participation; laboratory experiments performed by the students in the presence of the teacher, with experiment tracks provided in advance.

Partial tests consist of three exercises that must be solved in three hours, cumulative tests consist of four exercises (two exercises for each module) that must be solved in four hours. Students who have received a grade of at least 15/30 in each of the partial tests or in the final written exam are admitted to the oral exam. The oral exam consists in the discussion of the written test(s) and in two questions on the course topics, one for each module. The number of questions may be increased, either to achieve an excellent mark, or to reach the level required to pass the exam.
