Abstract

Magnetic measurements were performed on steel cables subjected to a magnetic field and the response measured without contact using Faraday's law, to estimate the effect of temperature and corrosion on magnetic properties of structural steel. Magnetic measurements were compared with electrochemical measurements to correlate corrosion quantitatively in terms of mass loss. The results obtained from the present work are helpful in bounding the achievable sensitivity for conventional magnetoelastic corrosion sensing and for suggesting the need for alternate techniques.
