The Eddy-current Method and Structure of Hardware for Search of a Condactive Body in a Zone of Highway

Often, conducting things with diamagnetic or ferromagnetic properties may be present in the overpass area (under the road or under the sidelines), which may be of particular value or threat, for example, to vehicles. Therefore, timely detection and disposal of such bodies are important. The article discusses the use of the eddy current method to search for such bodies.
