General physics II

Course objectives

Upon completion of the course the student will know the principles of electromagnetism, with particular reference to the concept of field, and to Maxwell's equations, and will have the basis for understanding electrical, magnetic, wave and optical phenomena. The student will be able to model and solve basic problems of electrostatics and magnetostatics and simple circuits in continuous currents. He will also be able to understand the basic principles of electromagnetic induction and the propagation of electromagnetic waves. During the course there are also some laboratory experiences on continuous and quasi-stationary current measurements and geometric optics. In the end the student will be able to use a digital multimeter and will have acquired the ability to process experimental data through the basic tools of statistics and measurement theory.

Teaching mode
Lectures with exercises and numerical examples. For laboratory experiences, students are divided into groups of three and personally take measurements in the didactic laboratory, following the text provided by the teacher. For each experience, a written report is foreseen by the student, alone or together with his group, which he will have to take during the oral examination. In the event that, due to the pandemic emergency, it is not possible to carry out lessons in person, the course modality will be of the blended or remote type depending on the regulatory provisions.
Frequency
Frequency is optional. If a student has not been able to carry out laboratory experiments for some reason, recovery days are to be arranged with the teacher.
Exam mode
Expected learning outcomes: Knowledge of the basic phenomena of electricity and magnetism and ability to deal with problems of electrostatics and magnetostatics and simple circuits in continuous current. Knowledge of Maxwell's equations and ability to identify the underlying physical principles. Knowledge and ability to solve problems of quasi-stationary circuits with capacitors and inductors. Knowledge of the main phenomena of magnetic induction, and ability to solve simple problems related to the electric and magnetic fields varying over time. Knowledge of phenomena related to the propagation of electromagnetic fields and ability to solve problems related to reflection, refraction and interference of electromagnetic waves. Assessment tools: Written test and oral exam. The written test consists of 4 exercises and 2 theory questions. The duration of the written test is 2.5 hours. No material can be used during the written test. The oral exam consists of three questions. Among the questions of the oral exam, questions related to the laboratory experiences carried out during the course may also occur. At the oral exam the student will have to bring the reports related to the laboratory experiences he has done during the course. Assessment methods: verification of the student's ability to understand and be able to apply the fundamental laws that regulate electrical and magnetic phenomena. A typical exam consists in: verification of the degree of knowledge of Maxwell's equations and their derivation, verification of the ability to deal with and solve typical problems of electrostatics and magnetostatics and exercises with simple circuits that have been carried out during the lessons, verification of the level of knowledge related to the phenomena of electromagnetic induction, both from the theoretical point of view and through simple exercises, verification of the typical phenomena of electromagnetic waves: transported power, reflection, refraction and interference. Evaluation criteria: Each exercise of the written test is worth 6 points and each theory question is worth 3 points. The written test is considered passed if the student reaches the mark of 18. Each theory question at the oral exam is worth 10 points. The final mark is an average between the written and oral test marks.
