Magnetostatics in vacuum. Magnetic field. Lorentz's force, path of a charge in magnetic field. Hall effect. Elementary Laplace's laws. Ampère's theorem. Vector potential.
Magnetic fields in matter. Orbital and spin momenta. Magnetisation. Auxiliary field H. Diamagnetism, paramagnetism, ferromagnetism.
Fields slowly changing in time. Electromagnetic induction. Faraday-Neumann-Lenz's law. Displacement current. Ampère-Maxwell equations.
Relativistic electrodynamics. Tensor field. Maxwell equations in covariant form.

Lectures and practical exercise sessions organised by the tutors.

The exam consists of a written test, shortly followed by an oral test. The written test will contain problems and theory questions, and it represents the largest fraction of the exam. During the semester, tutors will organise simulations, in view of the final exam.

The course foresees tutoring in support to the frontal lectures. The tutors will organise working groups dedicated to the problem and the previous written exams solutions and discussions.
