When the cylinder is made of a highly electrically conductive material, the induced oscillating current flows only at the surface. In contrast, if the cylinder is composed of a material with small conductivity, e.g. $\\sigma = 10^{-3}\\text{eV}$, the electric current flows inside the bulk of the cylinder.
