✦ Synopsis

Planar magnetic effect on an electrolytic system is studied. The observation ofa sine oscillation in current density perpendicular to the primary current in the system is reported. It has heen shown that the amplitude of this oscillation of mass transfer varies with the external magnetic field, ion content of the electrolyte and the freauency of the rotatina maanetic field. The coefficient of the planar magnetic effect is estimated. _ _ -_ INTRODUCITON Magnetoelectrolytic study has been an interesting problem in recent years. Theoretical and experimental works have been thoroughly undertaken by many researh investigators, such as, Falkenhagen and Ebeling[l], Friedmann[2], Mohana and Fahidy 3 , Wassef and Alemah[4] and Lielmezs and Fahidy El 5 .

However, among all the previous works, the second order magnetic effect on an electrolytic system is scarcely considered and very few experimental data have been found. To remedy this, Yau[q was able to propose a phenomenological theory in which the second-order effect is taken into account. The purpose of this paper is to conduct an experiment in an isothermal system to study the planar magnetic effect and to estimate the coefficient of this second-order effect. Furthermore, the previous experiments were performed under the influence of a stationary magnetic field. In this work we aiso intend to study the effect of a rotating magnetic field on mass transfer in an electrolytic system.
