Consider a plasma in a strong constant magnetic field with self-consistent electric field. We present here the formal derivation that leads to the so-called guiding center approximation, and justify it in the case of a well-prepared initial density of particles. More precisely, we prove that the motion of the particles can be approximatively decomposed as the sum of a fast rotation on Larmor circles, an advection along the magnetic lines and a small drift orthogonal to both electric and magnetic fields.
