Cathodic polarization curves were measured using electrolytes of 0.01-0.05mol·dm-3 Pb (CH3COO)2-0.5-3mol·dm-3CH3 COONH4 containing 0-0.5g/dm-3 gelatin. At a magnetic flux density of 0.12T, polarization decreased, the limiting current density increased, and the formation of dendrites was inhibited. Current efficiency increased by 10%. It was considered that the thickness of the diffusion layer decreased due to Lorentz force.
