Abstract	The remote field effect is an electromagnetic method for inspecting pipes and tubing. It has recently been commercialised as a technique for inspecting gray cast iron and ductile iron water mains. How-ever,commercial tools provide information on pits depths in the pipe and overall wall loss. Models of themechanical behaviour of cast iron pipe also require information on pit width and length. This paper discussesremote field effect apparatus and experimental techniques used in the laboratory to produce three dimensionalelectromagnetic field maps. The maps shown in the paper indicate that sizing corrosion pits in threedimensions is possible using the remote field effect. Further research needs are also discussed.
