Concepts and methods from 1st year courses. In particular: vector calculus identities, derivatives, theorems on gradient, divergence and curl (Stokes and Gauss).

Learning of electromagnetism principles and laws, stationary and time-dependent, including simple analysis methods. The student should be able to calculate electric and magnetic fields of simple charge/current distributions, applying such concepts to simple devices like capacitors and inductors. He should be able to analyze simple e.m. induction phenomena with time-varying fields and circuit shapes. Basic e.m. wave properties should be understood: polarization, intensity, refraction/reflection, interference and geometrical optics.

Electric phenomena in vacuum
Coulomb force; electric field, potential energy and electric potential
Electrical phenomena in dense media
Conductors, capacitors, dielectrics, electric current
Magnetic phenomena in vacuum
Lorentz force, magnetic field, Biot-Savart law, Ampère law, induction
Magnetism in the matter
Fields M and H
Electromagnetic waves in vacuum
Maxwell equations, energy, power and intensity of the field, radiation pressure
Interference, diffraction and polarization
Waves in dense media
Reflection, refraction, optics.

Lectures (hour/year): 64
Exercise classes (hour/year): 12
Practical activities (hour/year): 0
Lectures are based on explanations and practical examples, using the blackboard.
Exercise classes consists in solution of problems and exam exercises on the blackboard, encouraging students’ active participation.

Reference textbooks: Serway (easier, more intuitive), ISBN 9788879598248 or Mazzoldi-Nigro-Voci (more complete and formal, more difficult overall), ISBN 8879591525.
There are many equivalent textbooks, however. See the course's website.
Brief lectures videos prepared by the teacher (2016/17) and covering the whole course are available on the e-learning platform KIRO, including notes and useful links:
see http://www.unipv.it/fis/fisica2/EleInfoBio/index.pdf (some topics have been dropped or treated in a simpler way in later years).

Final exam will be written, with optional oral (24/30 maximum possible score for written exam).
The written exam lasts 2h and consists of 6 exercises. Correct solution of 2-3 of them normally is sufficient for a positive exam.
The oral exam starts with a revision of the written part, then further questions on general topics of the course will be asked, their complexity depending on the student’s preparation. Oral exam takes usually 15-20 minutes.
While written exams in physical classroom will be impossible due to COVID emergency, the exam will be only oral: 30 min max, questions on 4 main topics (E, B static fields, e.m. induction, waves/optics).
