FIELD: the invention refers to the means of electromagnetic detection of objects in the ground different on electro conductivity and magnetic penetrability from rocks.
SUBSTANCE: the inductive transformer has a magnetic core with a winding out of electro conductive material and a matching amplifier. The magnetic core is fulfilled in the shape of a tube formed by parallel to each other magnetic rods isolated between themselves. The transverse calibers of the rods are several times smaller then the transverse dimensions of the tube. The tube is provided with a casing. The transformer may have three magnetic cores in the shape of tubes provided with casings. The casings are connected in such a way that their axles are mutually orthogonal and rigidly fastened for forming a tripod.
EFFECT: reduces the threshold of sensitiveness, increases accuracy of measuring.
