ed. EdiSES - Educational objectives
- Understanding the basics of electromagnetism and familiarity with the solution of simple problems related to the subject matter.
- Prerequisites
- In order to be able to understand and to apply the majority of the techniques described within the course, the student must be familiar with:
differential and integral calculus
vectors
fundamentals of physics, e.g. cynematics and dynamics, conservative forces, potential energy, as treated in the Course of "Fisica Generale I".
Knowledge of these techniques represents an important prerequisite for students planning to follow this course with profit. - Teaching methods
- Lectures: explanation of the theoretical arguments and prompt application with exercises.
- Other information
- Even if not strictly mandatory, attendance to the lectures and exercises is highly recommended
- Learning verification modality
- Final exam consisting of a written test of 2 hours with 5 exercises (˜10 questions) to be solved plus an optional colloquium of ˜30 minutes on the main topics of the course and a discussion on the test.
The colloquium is foreseen only for students who passed the test and want to improve their score.
Examples of tests of previous years are available online on the Unistudium platform. - Extended program
