Course Objectives
General Physics II: Electrostatics and Electromagnetism.
The training objective of the General Physics II course is to transfer to the students the basic concepts and physical laws underlying electromagnetism. Particular attention is paid to the methodology for solving simple electrostatics and electromagnetism problems by applying Maxwell's equations.
Knowledge and understanding: upon passing the exam, the student knows and has understood the laws of electrostatics, electrical conduction, the magnetic phenomena, the laws that bind electric and magnetic fields that vary over time.
Applying knowledge and understanding: upon passing the exam, the student is able to apply the theoretical knowledge acquired to the resolution of simple electrostatic, magnetostatic and electromagnetism problems using Maxwell's fundamental principles and equations.
Making judgments: upon passing the exam, the student is able to critically examine the results obtained in solving problems. Following the passing of the exam, the student will be able to recognize situations in which to apply the acquired skills, to identify the type of problem and to independently evaluate possible alternatives for its resolution.
Communication skills: following the passing of the exam, the student is able to communicate the knowledge acquired through a technical-scientific language suitable for specialist and non-specialist interlocutors.
Learning skills: following the passing of the exam, the student is able to autonomously deepen the knowledge acquired and apply them independently to the study of new topics to be addressed in the continuation of his / her engineering study path.
Course Prerequisites
No mandatory prerequisites. It is recommended to have acquired the fundamental concepts of General Physics 1 and Mathematical Analysis 1 and 2.
Teaching Methods
Assessment Methods
The exam consists of two tests, one written and one oral.
The written test is intended to ascertain the student's ability to apply the knowledge acquired during the course to the resolution of simple problems of electrostatics, magnetostatics and electromagnetism. Passing the written test allows access to the oral test.
The oral exam is aimed at ascertaining the level of knowledge and understanding of the course contents (electrostatics, magnetostatics, electromagnetism), assessing autonomy of judgment, communication skills and learning skills. The oral test consists in the discussion of the written test, in questions and/or exercises on the course contents.
The final mark of the examination is determined taking into account both the written and oral tests.
