It is well known that magnetic fields are associated with current flow; thus electrochemical reactions should have an associated magnetic field. The detectability of the magnetic field will depend on the magnitude and the spatial distribution of the corrosion currents. The current distribution can be determined by inserting probes into the electrolyte, but the presence of such probes may distort the current distribution being measured. Therefore the use of magnetic means provides a non-invasive method which may be capable of monitoring both the magnitude and the spatial distribution of the corrosion currents. First reports of such measurements are presented here.
