Primary aluminum is produced in electrolytic cells where bath and metal flow due to Lorentz Forces. This work presents the experimental validation in real pots of a previously introduced 3-D magnetic field analysis methodology develop with the commercial Finite Element package ANSYS 9.0. Numerical results represent fairly the most important components for the simulated technology (B X and B Y), considering the measurement error e. Maximum differences observed between experimental and numerical results are 33% for B X and 60% for B Z. Correlation between measured and calculated values are up to 98,8% for B X and 93,5% for B Z.
