摘要：
The mathematical model for an induction detector intended for detection of metal impurities is examined. The detector consists of three coils. The centre coil serves to induct a magnetic moment in the metal sample, and side coils are used to record this moment during the sample propulsion through the detector. It is shown that at an identical value of the magnetic field induction, created by the induction coil in the unit volume of the sample, the induced magnetic moment is defined by magnetic susceptibility for ferromagnetics, and for nonmagnetic materials - by their electric conductivity.
