Two options for constructing an attached induction transducer for detecting steel objects in an iron ore stream on a conveyor belt are compared theoretically and experimentally. The options in which testing covers the entire conveyor belt width and where the stream width is divided into “tracks” are considered. A significant effect of magnetic interaction between rock particles magnetized by the eddy current transducer field is revealed. It has been shown that magnetizing ore stream locally can provide substantially better conditions for the selective detection of undesirable steel inclusions in the iron ore stream than across the entire stream width. However, the latter option is feasible only given certain proportions between the transducer dimensions and the conveyor belt width. The results of experimental verification are in satisfactory agreement with theoretical estimates.
