The suppression of superconductivity of the first kind in a hollow cylindrical superconductor by a strong electric current is studied on the basis of the linear time-dependent Ginzburg-Landau equations. Due to the presence of an electric field, mixed state consisting of superconducting fluctuations is established at the inner surface of the sample close to some critical current. When the inner radius r{sub 1} of the cylinder is of the order of magnitude of the superconducting coherence length {xi}, the magnetic response to a longitudinal magnetic field H{sub a} shows an oscillatory dependence of the magnetic flux on r{sub 1}/{xi} and H{sub a} due to the quantum character of the macroscopic wave function. In the limiting situations r{sub 1} {much gt} {xi} and r{sub 1} = 0 we find again the paramagnetic and diamagnetic effect of the two- and one-dimensional mixed states respectively.
