27535 - Physics 2

Learning outcomes

At the end of the course the student acquires a fundamental knowledge on the electric and magnetic phenomena. He/she knows how to use the acquired knowledge to solve simple problems related to the creation of electric and magnetic fields, to the conduction and induced currents, to the particle motion in e.m. fields, and to the propagation of e.m. waves according to geometric and wavelike optics.

Course contents

• Electrostatic field and its properties. Capacitors, electric current, resistors and simple circuits.

• Magnetostatic field and its properties. Lorentz force.

• Electric and magnetic properties of matter: polarization and magnetization.

• Time-dependent electromagnetic phenomena. Electromotive force, inductors and oscillating circuits.

• Maxwell equations.

• Electromagnetic waves. The electromagnetic spectrum. Interference, diffraction, polarization.

Teaching methods

Lectures and exercises in the lecture-hall.

The exercises carried out by the lecturer aim to consolidate the knowledge of the arguments treated, by means of specific quantitative examples.

The slides shown during the lessons and the solved exercises will be made available on Virtuale.

Assessment methods

The final examination serves to assess the student's level of understanding of the topics covered and their understanding of the fundamental principles of electromagnetism (including electromagnetic waves).

The exam is written and consists of theoretical questions and exercises. There are 5 questions, and the score is +3 for a correct answer, +1.5 for an incomplete answer, and 0 for an incorrect or missing answer. There are 3 exercises, each with a score ranging from 4 to 7 depending on their difficulty (the maximum total score for the 3 exercises is 17). Each exercise is awarded full points if completed correctly, half points if correct but incomplete, and 0 points if completed incorrectly or missing.
The maximum score awarded for each question/exercise will be clearly indicated on the assignment.
Calculation errors count -0.5; errors in the unit of measurement (incorrect or missing) count -1.
Students have 2 hours for the written exam. The use of support materials such as textbooks, notes, or smartphones is prohibited during the exam. Calculators are permitted.
A sheet of paper with the fundamental constants will be provided by the instructor.

The maximum score achievable is 30 cum laude.
The exam is passed with a minimum score of 18/30.

Retaking the exam is possible, but only the grade for the last submitted assignment will be valid until it is registered. All grades from previous attempts will be cancelled.

The exam must be combined with the Physics 1 exam to be able to register the 12 credits.

Students with learning disabilities or temporary or permanent disabilities: please contact the relevant University office promptly (https://site.unibo.it/studenti-con-disabilita-e-dsa/it ). The office will advise students of possible adjustments, that will be submitted to the professor for approval 15 days in advance. He/she will evaluate their suitability also in relation to the academic objectives of the course.
