Prerequisites:

Elements of algebra, calculus and physics as learned in the maths and physics courses of the previous year 
Target skills and knowledge:

Mastering of the fundamental laws of electromagnetism, allowing to solve simple problems.
Getting familiar with laboratory instrumentation (multimeter, oscilloscope, function generators), with the ability to elaborate the measured quantities and report on them. 
Examination methods:

A written test allowing to access the oral examination.
The written test consists of a few numerical problems, and possibly a few conceptual questions. 
Assessment criteria:

The final evaluation takes into account results of the written and oral test, and the laboratory reports. 
Course unit contents:

Electrical charge, Coulomb's law, discrete and continuous charge distributions. Electrostatic field and potential.
Gauss' law.
Conductors in equilibrium, capacitors, electrical energy density and pressure.
Electrical properties of matter, polarization, electric field in the presence of dielectrics.
Electrical current and current density. Continuity equation.
Laws of Ohm and Kirchoff, simple linear circuits, Joule effect. Charging and discharging a capacitor.
Magnetic field B. Lorentz force and motion of charges in a Bfield. Cyclotron, mass spectrometer, velocity selector.
Sources of the magnetic field B: laws of Laplace and BiotSavart. Forces acting on a conductor carrying current. Magnetic field of a coil, finite and infinited solenoid. Magnetic dipole.
Laws of Ampère and AmpèreMaxwell, displacement current and B field of an infinite wire and solenoid, and a toroidal solenoid.
Divergence and rotor of B. Stokes' theorem. Vector potential.
Magnetic properties of matter, magnetization, magnetic field in the presence of dia, para and ferromagnetic materials.
Law of FaradayLenz. Flux linkage, self and mutual induction.
Magnetic energy and energy density. RL, LC and RLC circuits.
Maxwell's equations, integral and differential.
Wave frequency, wave number and velocity. Progressive and stationary waves, interference, beats.
Plane EM waves, derivation from Maxwell's equations in the vacuum, speed of light. Poynting vector. Intensity, power and momentum of a wave, radiation pressure.
Polarization. Spectrum of EM waves. Refraction index and Snell's law.
Blackbody radiation, Stefan's and Plank's law. Photoelectric effect and waveparticle duality.
The examples discussed in the classes, the methods and instrumentation utilized in the laboratory are also integral to the course. 
Planned learning activities and teaching methods:

Lectures, approximately 60% theoretical and 40% concerning problems and examples. Completed by three laboratory experiments. 
Additional notes about suggested reading:

Besides the textbook, slides of the lectures, and guides to the laboratory experimentes will be available online. 
Textbooks (and optional supplementary readings)
