Electric and Magnetic Field Interactions with Materials
... Because the interactions of E and B with materials are too complex to keep track of in terms of individual charges, three parameters are defined to account for these interactions on a macroscopic scale. Induced polarization and alignment of permanent electric dipoles is accounted for by permittivity ...

Hall effect
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
