| KNOWLEDGE AND UNDERSTANDING: THE COURSE INTENDS TO GIVE THE EXPERIMENTAL OPERATIVE COMPETENCES AND A GOOD KNOWLEDGE ON THE EXPERIMENTAL ANALYSIS OF THE PROPERTIES OF THE MAGNETIC FIELD, ON ITS INTERACTION WITH THE ELECTRICAL CURRENT, AND ON THE PHENOMENOLOGY RELATED TO THE MAGNETIC PROPERTIES OF THE MATTER. APPLYING KNOWLEDGE AND UNDERSTANDING: ONE OF THE MAIN GOALS IS TO MAKE THE STUDENT ABLE TO OPERATE WITH COMPETENCE IN A LABORATORY, AND TO DEVELOP THE SKILLS TO SOLVE PRACTICAL EXPERIMENTAL PROBLEMS. MOREOVER THE COURSE WILL GIVE A CONTRIBUTION TO REFINE THE POWERS OF OBSERVATION OF THE MAGNETIC PHENOMENA, ALSO IN THE EVERYDAY LIFE. IN PARTICULAR, DURING THE COURSE, SEVERAL EXPERIMENTAL GOALS WILL BE GIVEN, AND EACH STUDENT WILL HAVE TO REACH THEM BY SOLVING, ALSO IN CREATIVE WAY, A SERIES OF INTERMEDIATE PROBLEMS. EVERYTHING WILL BE DONE UNDER THE SUPERVISION AND THE CONTROL OF THE PROFESSOR, WHO WILL PROVIDE FOR ADDRESSING EACH SINGLE STUDENT TOWARDS THE MOST APPROPRIATE SOLUTION WHICH, HOWEVER, WILL HAVE TO BE REACHED AUTONOMOUSLY. COMMUNICATION SKILLS: THE COURSE WILL TEND TO PROMOTE THE ABILITIES OF THE STUDENT TO FACE, ANALYZE AND SOLVE A GIVEN PHYSICAL PHENOMENA CONCERNING THE MAGNETISM, AND TO EXPRESS IN A CLEAR AND RIGOROUS WAY (BY MEANS OF WRITTEN REPORTS) THE PERFORMED ANALYSIS AND THE SOLUTIONS FOUND. AT THE END OF THE COURSE, THE STUDENT WILL HAVE TO BE ABLE TO DISCUSS IN A PROPER WAY THE SINGLE REALIZED EXPERIMENTS. MAKING JUDGEMENTS: THE STUDENTS ARE GUIDED BY THE PROFESSOR TO FACE, AUTONOMOUSLY, IN A CRITICAL WAY, AND WITH LOGIC AND RESPONSIBILITY, THE TARGETS OF THE VARIOUS EXPERIMENTS. HOWEVER THE ERRORS, THAT EVENTUALLY WILL BE DONE BY THE STUDENTS, WILL BE CONSIDERED AS OCCASIONS FOR DISCUSSIONS, REASONING AND LEARNING, RATHER THAN AS PENALIZATION AND DISINCENTIVE TO THE OPERATIVE AUTONOMY. |
| Prerequisites | |
|---|---|
| PREREQUISITES: IT IS NECESSARY TO KNOW THE BASIC THEORY CONCERNING THE ELECTRICAL CIRCUITS, THE ELECTRICAL CURRENT AND THE AC AND DC MAGNETIC FIELDS, AS WELL AS THE PHYSICS RELATED TO THE GENERATION OF MAGNETIC FIELDS AND TO THEIR EFFECTS ON THE MATTER. IT IS REQUESTED TO KNOW ALSO THE EXPERIMENTAL BASIC CONCEPTS CONCERNING THE ELECTRICAL CIRCUITS AND THE INSTRUMENTS USED FOR THEIR ANALYSIS. |
| Contents | |
|---|---|
| THEORY: - A BRIEF SUMMARY OF THE LAW OF ELECTROMAGNETISM; - THE MAGNETIC PROPERTIES OF THE MATTER: PHENOMENOLOGY; - METHODS FOR THE TREATMENT OF THE PROBLEMS RELATED TO THE GENERATION, MEASUREMENT AND USE OF THE MAGNETIC FIELDS; - THEORIES AND TECHNIQUES FOR THE MEASUREMENTS AND THE ANALYSIS OF THE MAGNETIC PROPERTIES OF THE MATTER; - TECHNOLOGIES AND EQUIPMENT FOR THE STUDY OF THE MAGNETISM IN DC AND AC FIELDS; - HOW TO SOLVE A MAGNETIC PROBLEM BY MEANS OF A SOFTWARE FOR FINITE ELEMENTS ANALYSIS (FEMM2); - THE MAGNETIC PROPERTIES OF THE SUPERCONDUCTORS AND THEIR IMPORTANCE FOR THE APPLICATIONS; - THE INSTRUMENTS AND EQUIPMENT THAT ARE PRESENT IN A LABORATORY FOR THE RESEARCH OF THE MAGNETIC PROPERTIES OF THE MATTER. LABORATORY: THE COURSE INCLUDES 8-10 LABORATORY EXPERIMENTS: 1) MEASUREMENT OF THE MAGNETIC FIELD PRODUCED BY A FINITE SOLENOID, AND ANALYSIS OF THE DIFFERENCES AND ANALOGIES RESPECT TO THE IDEAL CASE; 2) MEASUREMENT OF THE INTERACTION BETWEEN THE ELECTRICAL CURRENT AND THE MAGNETIC FIELD; 3) MAGNETIC MATERIALS: MEASUREMENTS OF THE MAGNETIC PERMEABILITY BY USING A HALL PROBE ; 4) DETERMINATION OF THE INTENSITY OF MAGNETIZATION OF A FERROMAGNETIC ROD WITH THE METHOD OF THE SOLENOID AND THE COMPASS; 5) MEASUREMENT OF THE MAGNETIC FORCE AND OF THE MAGNETIC MOMENT OF A FERROMAGNETIC SAMPLE BY USING A COUPLE OF HELMHOLTZ COILS; 6) MEASUREMENT OF THE MAGNETIC PERMEABILITY OF A MATERIAL BY MEANS OF A RESPONSE OF A RL CIRCUIT TO A SQUARE WAVE; 7) MEASUREMENT OF THE MAGNETIC PERMEABILITY OF AIR; 8) MEASUREMENT OF THE SPACE DEPENDENCE OF THE FORCE BETWEEN TWO PERMANENT MAGNETS; 9) REALIZATION AND CALIBRATION OF A SIMPLE INSTRUMENT FOR MAGNETIC MEASUREMENTS; 10) COMPARISON BETWEEN THE MEASURED FIELDS AND THOSE CALCULATED BY USING FEMM2, FOR A GIVEN CONFIGURATION OF 1 OR 2 SOLENOIDS. |

|---|---|
| THE EVALUATION WILL BE DONE BY MEANS OF A FINAL EXAM, WHERE ALSO THE INTRA-COURSE WRITTEN REPORTS, ABOUT THE PERFORMED EXPERIMENTS, WILL BE DISCUSSED. FOR THIS REASON, IN ORDER TO PERFORM ALL THE EXPERIMENTS, IT IS NECESSARY THAT THE STUDENTS FOLLOW ALL THE LECTURES. IF THE INTRA-COURSE WRITTEN REPORTS WILL BE CONSIDERED SUFFICIENT, IT WILL BE POSSIBLE TO MAKE THE FINAL EXAM. |
