|---|---|
| THE COURSE FOLLOWS THE ONE CONCERNING THE PHYSICAL CONCEPTS OF CLASSICAL MECHANICS AND GEOMETRIC OPTICS, AND IS SUITABLY ORGANIZED IN ORDER TO GIVE TO THE STUDENTS THE BASIC KNOWLEDGE OF THE FUNDAMENTAL PRINCIPLES OF THE CLASSICAL ELECTROMAGNETISM AND OF THE UNDULATORY OPTICS. THE MAIN ACQUIRED KNOWLEDGE WILL BE: -THE DESCRIPTION AND THE TRATMENT OF THE ELECTRICAL FORCE, FIELD AND POTENTIAL, DUE TO DISCRETE AND CONTINUE CHARGE DISTRIBUTION -THE CHARACTERISTICS OF THE ELECTRICAL CURRENT, RESISTANCE AND CAPACITY, BOTH FROM THE MACROSCOPIC AND MICROSCOPIC POINT OF VIEW, AND THE ELETRICAL CIRCUIT ANALYSIS -THE MAGNETIC FIELD, ITS PRODUCTION, ITS ASSOCIATED ENERGY, AND ITS INTERACTION WITH THE MATTER -THE ELECTROMAGNETIC WAVES, THEIR CHARACTERISTICS AND PROPAGATION IN THE SPACE THE MAIN SKILLS THAT WILL BE DEVELOPED WILL BE: -THE ABILITY TO UNDERSTAND/LEARN AUTONOMOUSLY THE RELATIVE ADVANCED CONCEPTS (PHYSICO-CHEMICAL) -THE ABILITY OF MODELLING REAL SYSTEMS MADE BY ELECTRICALLY CHARGED OBJECTS, OR IN PRESENCE OF ELECTRIC CURRENT, OR WITH MAGNETIC MOMENTUM/PROPERTIES -THE POSSIBILITY TO FACE THE RESOLUTION OF APPLICATIVE (PHYSICO-CHEMICAL) PROBLEMS CONCERNING THE CLASSIC ELECTROMAGNETISM -THE RIGHT VOCABULARY TO PRESENT IN A CRITICAL WAY THE ACQUIRED KNOWLEDGE |

| Teaching Methods | |
|---|---|
| THE COURSE IS ORGANIZED IN 60 HOURS OF CLASSROOM LECTURES AND EXERCISE/EXAMPLES (6 CFU). IT IS NOT MANDATORY TO ATTEND THE LECTURES BUT IT IS STRONGLY RECOMMENDED. ALL THE EXPLAINED CONCEPTS ARE STRENGTHENED WITH THE HELP OF EXAMPLES OF THEIR APPLICATION TO SOME TYPICAL PROBLEMS OF ELECTROMAGNETISM, AND WITH THE CORRELATION TO PHENOMENA IN THE DAILY LIFE. ALL THE MOST RELEVANT CALCULATIONS NECESSARY TO ALL THE TOPICS COVERED ARE PERFORMED AND CLARIFIED. |
| Verification of learning | |
|---|---|
| THE ACQUIRED KNOWLEDGE IS CERTIFIED FIRST BY A WRITTEN AND THEN BY AN ORAL EXAM. IN PARTICULAR: -FOR THOSE STUDENTS WHO ATTEND WITH PROFIT THE LECTURES, TWO WRITTEN PROOFS ARE PLANNED DURING THE COURSE. EACH PROOF CONSISTS OF A SERIES OF EXERCISES. THOSE STUDENTS WHO OBTAIN AT LAST 18/30 POINTS CAN – BUT NEED NOT – BYPASS THE FINAL WRITTEN EXAMINATION. THOSE STUDENTS WHO OBTAIN AT LAST 27/30 POINTS CAN – BUT NEED NOT – BYPASS THE FINAL WRITTEN AND ORAL EXAMINATION ABOUT THEORY, BUT WILL HAVE JUST TO DISCUSS ABOUT THE RESOLUTION OF THE EXERCISES SOLVED IN THE WRITTEN PROOFS. -FOR THOSE STUDENTS WHO DID NOT ATTEND WITH PROFIT THE LECTURES OR DID NOT ATTEND THE LECTURES AT ALL: ONE WRITTEN PROOF WITH PROBLEMS. AT LAST 15/30 POINTS ARE NEEDED FOR THE ADMITTANCE TO THE ORAL EXAMINATION. THOSE STUDENTS WHO OBTAIN AT LAST 27/30 POINTS CAN – BUT NEED NOT – BYPASS THE FINAL ORAL EXAMINATION ABOUT THEORY, BUT WILL HAVE JUST TO DISCUSS ABOUT THE RESOLUTION OF THE EXERCISES SOLVED IN THE WRITTEN PROOFS. THE ORAL EXAMINATION IS INTENDED TO BE COMPREHENSIVE OF THE EVALUATION OF ALL THE CONCEPT OF ELECTROMAGNETISM AND OPTICS INDICATED IN THE PROGRAM OF THE COURSE. THE FINAL POINTS WILL DEPEND ON THE POINT RECEIVED AT THE WRITTEN AND ORAL EXAMINATIONS. |
