Conduction properties become much more interesting once we turn on both and electric field $\mathbf{E}$ and magnetic field $\mathbf{B}$.
Conduction properties become much more interesting once we turn on both the electric field $\mathbf{E}$ and magnetic field $\mathbf{B}$.
Let us consider a conductive wire with current $\mathbf{j}$ flowing along the x-direction (notice how we are specifying the direction of the current and not of the electric field).
A magnetic field $\mathbf{B}$ acts on the wire along the z-direction, like shown in the figure:
