Résumé :
I review the modern (as well as some of the classical) results about the phase structure of Quantum Chromodynamics in a strong magnetic background. After a wide Introduction, I will show results about my recent model study of deconfinement and chiral symmetry restoration in a strong magnetic field. The main result is that, within the model, the deconfinement and chiral crossovers of QCD in strong magnetic field are entangled even at the largest value of $B$ considered in numerical computations, namely $eB=30 m_\pi^2$ (that is, $B \approx 6\times 10^{15}$ Tesla). I finally compare the phase diagram of this model with previous results, as well as with available Lattice data.
