OBIETTIVI E CONTENUTI

OBIETTIVI FORMATIVI

The specific training objective is to provide the student with the ability to solve elementary but concrete problems. This implies that the student must know how to distinguish between fundamental concepts (electric and magnetic fields and forces, works, Gauss's laws, Ampere's, Faraday's, ...) and more specific issues (motion of charges in electromagnetic fields, cylindrical condensers, .. .) demanding a thorough understanding of fundamental concepts.

MODALITA' DIDATTICHE

Lessons, seminars, discussion of case studies
