	Teaching Methods
	THE COURSE IS ORGANIZED IN LECTURES EXPLAINING THE FUNDAMENTAL CONCEPTS OF ELECTROMAGNETISM. EACH LECTURE IS DEVOTED TO THE THEORETICAL INTRODUCTION OF ONE OR MORE TOPICS FOLLOWED BY EXAMPLES AND APPLICATIONS. MATHEMATICAL CONCEPTS ARE INTRODUCED IN PARALLEL WITH THE PHYSICS TOPICS.

	Verification of learning
	THE ACHIEVEMENT OF THE TEACHING OBJECTIVES IS CERTIFIED BY PASSING AN EXAM. EXAMINATION IS GRADED ACCORDING TO A SCALE RANGING FROM 0 TO 30, WITH 18 AS A PASS MARK. THE EXAM INCLUDES A WRITTEN TEST (WHICH MAY BE DIVIDED INTO TWO IN ITINERE TESTS) AND AN ORAL EXAM THAT TAKE PLACE ON DIFFERENT DAYS, ACCORDING TO A PRE-ESTABLISHED CALENDAR. ACCESS TO THE ORAL EXAM IS ALLOWED TO STUDENTS WHO HAVE PASSED THE WRITTEN TEST (PASS MARK: 15/30). IN THE WRITTEN TEST THE STUDENT MUST DEMONSTRATE TO KNOW THE FUNDAMENTALS OF ELECTROMAGNETISM, DISCUSSING AND SOLVING TWO OR THREE PROBLEMS. THE TEST HAS A DURATION OF TWO HOURS. THE ORAL EXAM IS AIMING AT EVALUATING THE STUDENT'S ABILITY TO CRITICALLY DISCUSS SIMPLE SITUATIONS RELATED TO ELECTROMAGNETISM OR OPTICS. THE ABILITY TO FORMULATE MODELS AND DISCUSS THEIR IMPLICATIONS IN THE LIGHT OF THE CONCEPTUAL FRAMEWORK PRESENTED DURING THE COURSE IS EVALUATED DURING THE ORAL EXAM. THE FINAL GRADE IS OBTAINED FROM THE AVERAGE PERFORMANCE IN THE WRITTEN TEST AND THE ORAL EXAM. THE MINIMUM MARK FOR PASSING THE EXAM IS 18/30. THE “LODE” (MAXIMUM GRADE WITH DISTINCTION) CAN BE GIVEN TO STUDENTS WHO OBTAIN A GRADE OF 30/30 AND SHOW THAT THEY ARE ABLE TO AUTONOMOUSLY USE KNOWLEDGE AND SKILLS IN CONTEXTS WHICH ARE NEW OR NOT DISCUSSED DURING THE COURSE. THE EXAMS CAN BE TAKEN IN THE FOLLOWING WAYS: (A) WRITTEN TESTS DURING THE COURSE (IN ITINERE WRITTEN TESTS) AND FINAL ORAL EXAM. STUDENTS ARE ADMITTED TO THE ORAL EXAM WITH A MINIMUM GRADE OF 15/30 (AVERAGE GRADE ON IN ITINERE WRITTEN TESTS). (B) PERIODIC WRITTEN TESTS WITH AN ORAL EXAM ACCORDING TO THE CALENDAR SET BY THE TEACHING COUNCIL (CONSIGLIO DIDATTICO) FOR THOSE WHO HAVE NOT TAKEN OR PASSED THE IN ITINERE WRITTEN TESTS. CANDIDATES WHO HAVE OBTAINED THE PASS MARK OF 15/30 ARE ADMITTED TO THE ORAL EXAM.
