This chapter shows the main ideas of the derivation of the MHD and Hall-MHD equations (Sect. 1) and provides a brief survey of qualitative properties of these equations (Sect. 2). Some results that concern the role of the pressure in the theory of the MHD equations are presented in Sect. 3, and one local regularity criterion for suitable weak solutions to the MHD equations, which uses the behavior of the L3-norm of the velocity and the magnetic field as t approaches the hypothetic singular time t0, is presented in Sect. 4.
