Engineering Physics Annotation << Back ON NEGATIVE MAGNETORESISTANCE AND DARK ELECTRIC CURRENT IN LIQUID S.A. GERASIMOV Dark electric current occurs not only when aluminum comes into contact with a liquid, but also with the participation of copper electrodes. The same goes for negative magnetoresistance, as a result of which the effect of a magnetic field on liquid with two asymmetrical electrodes increases the electromotive force, generated by such a power source. Particular attention is paid to the role of heating liquid source of magnetic field. Processing of experimental results, aimed at studying the change in voltage drop from temperature changes, demonstrated a weak dependence of the strength of the dark electric current on liquid heating. Changes in voltages and temperature changes are not correlate neither in time nor in magnitude.
