Hall coefficient
= Hall coefficient
{c}
{title2=$R_H=E_y/(J_xB_z)$}
The <Hall coefficient> relates a transverse <electric field> to longitudinal <current density> and transverse <magnetic field>, with oriented axes as in the displayed formula. Its <SI> unit is $\mathrm{m^3/C}$. For one isotropic <Drude model> species it is $1/(nq)$; multiple <charge carriers> need not follow that formula.
