FIELD: nuclear-magnetic measurements. SUBSTANCE: device has surface excitation coil and receiving parallel circuit which is equipped with ferrite coils and is designed for generation of signal which is induced in said coils through communication coil to direct current SQUID. Surface coil is connected to said ferrite coil by means of mutual inductance, which value depends on magnetization of explosive of mine. EFFECT: increased validity of detection of mines in plastic jackets, increased distance of mine detection. 5 cl, 1 dwg
