  Multi-frequency eddy current measurements are utilized to conduct non-destructive testing of physical and geometric characteristics of products made from magnetic metallic materials. Using the example of magnetic bronzes, the joint effect of several parameters like magnetic permeability, electrical conductivity, the thickness of magnetic material, and the value of the gap between the material surface and the sensor on experimental hodographs of the “controlled sample - eddy current sensor” system is investigated. The influence of magnetic properties on hodograph lines is studied by comparing the results with hodographs of a non-magnetic copper alloy. The ...
