Abstract
The effect of electro-magnetophoretic forces on the gas bubbles in the electrolyte is considered for aluminium electrolytic cells. The model is derived for an additional pressure distribution resulting from the magnetic forces in the liquid electrolyte. According to the estimates, the integral force on an individual bubble exceeding 2 mm in size could be sufficient to overcome the typical drag force associated with electrolyte flow, opposing motion of the bubble along the slightly inclined base of the anode. This could explain certain feature of the anode effect onset
