On the 3D character of the magnetohydrodynamic effect during metal electrodeposition in cuboid cells

The influence of external homogeneous magnetic fields during electrochemical metal deposition in cuboid cells is shortly reviewed. By analytical means, supported by numerical simulations, it is shown that a simplified 2D approach is often misleading and has to be replaced by a more complex 3D treatment as only the solenoidal part of the Lorentz force can cause convection.
