Description
The effects of strong magnetic backgrounds on the properties of strongly interacting matter are the subject of growing theoretical interest, because of their possible phenomenological implications. In this talk I will review some recent results obtained by lattice QCD simulations, with a focus on the determination of the behavior of the free energy of the system as a function of the external field. I will discuss technical issues related to this determination and show that strongly interacting matter behaves as a paramagnet, with a magnetic susceptibility which steeply rises as one enters the Quark-Gluon Plasma phase. The magnetic field contribution to the equation of state of the system is discussed as well.
