The Magnetic Field

Following the observation of enhanced corrosion of parts of a seawater-immersed permanent magnet motor made from Ni-Al bronze, a laboratory study of the effect of uniform magnetic field on the corrosion of this alloy in a 3.5 wt% NaCl solution has been performed. The results have been compared with measurements of enhanced convection with a rotating disc electrode. The largest effect of the magnetic field was an enhancement of the anodic current density of 52% in a field of 800 mT. This enhancement was equivalent to that resulting from gentle stirring with the rotating disc electrode with diameter 10 mm at 20 rpm. The increase in corrosion current varied with the magnitude of both the magnetic field and the initial corrosion current, and increased with both. The effect can be explained in terms of the Lorentz force, and modeling was performed to quantify the flow induced in the electrolyte by this force.

The Magnetic Field

Effects of horizontal magnetic field paralleling to the iron electrodes with various configurations on the anodic behavior in sulfuric acid solution are investigated. The magnetic field effect is stronger for the horizontally placed upward electrode than for the horizontally placed downward and the vertically placed electrodes. Locally dissolution-mitigated regions are found at two ends of the electrode along the direction perpendicular to the magnetic field direction in addition to the locally accelerated dissolution region at two ends paralleling to the magnetic field direction. The effect of magnetic field on convection process is critical in determining the anodic current density.

The Magnetic Field

The stability of viscous flow between two coaxial cylinders maintained by a constant transverse pressure gradient is considered when the fluid is an electrical conductor and a uniform magnetic field is impressed in the axial direction. The problem is solved and the dependence of the critical number for the onset of instability on the strength of the magnetic field and the coefficient of electrical conductivity of the fluid is determined.
