Abstract
Two quite different mechanisms combine together to control the distribution of the magnetic field in a conducting material: diffusion, and convection. Their analysis, starting from the induction equation, is the subject of this chapter. A dimensionless number of fundamental importance, that we call the magnetic Reynolds number (Rm) enables the relative importance of each of them to be appreciated. In alternating regimes, identified by the skin effect, another dimensionless number, called the shielding parameter (R ω ) is also usefull; its value characterises the penetration of the magnetic field into the conducting domain.
