PHYSICS II

Course objectives

The aim of the course is to teach the basics of classical electromagnetism, both in vacuum and in isotropic and homogeneous media, in such a way that the student can understand simple problems and use the basic laws to solve them. The course includes both theoretical and exercise classes. The main knowledge acquired upon the course will be: - Description of electric phenomena in vacuum and in the matter. Interpretation of these phenomena in terms of electric field and electric potential. - Description of magnetic phenomena in vacuum and in the matter. Interpretation of these phenomena in terms of magnetic field and interaction between magnetic field and magnetic momentum of matter. - Description of the electromagnetic phenomena with respect their time evolution. Interpretation of these phenomena in terms of electromagnetic induction and electromagnetioc waves. The main skills developed during the course will be: - Ability to analyze and to solve simple problems about electric and magnetic phenomena such as: electrical conduction, calculation of electric and magnetic field in the space, calculation of interaction forces between electric charges or between wires bringing current and external magnetic fields, electromagnetic wave propagation. - Development of an analytic attitude leading the student to decompose a problem in sub-tasks which can be solved with the knowledge already acquired.

Attendance optional, but recommended
Exam mode
Written exam 5 problems Oral exam 3 questions on examples, application and demonstrations
Lesson mode
The exam consists of a combination of open-ended questions and theoretical and practical problems. Students will be required to demonstrate their understanding of the fundamental concepts of electromagnetism, solve mathematical problems, and analyze physical situations. The exam will be in written form and is expected to have a duration of 2.5 hours, followed by an oral examination. The use of non-programmable calculators is allowed.
