METHOD FOR ELECTRIC FIELD DEMONSTRATION Russian patent published in 1997 - IPC

FIELD: education. SUBSTANCE: method involves excitation of electric currents between metal electrodes in conducting liquid by means of electromagnetic field generator; and analysis of distribution of potential along surface of conducting liquid using two metal probes which are connected to different points on surface of conducting liquid through indicator. Liquid conductance is significantly less than conductance of electrodes. Probes are spaced from each other by given distance. method involves search for points in which indicator outputs maximal value. Equal potential lines and lines of electric field intensity are generated using coordinates of found points. EFFECT: increased functional capabilities. 3 dwg
