FIELD: electricity.
SUBSTANCE: device for nuclear magnetic resonance for core study contains a direct current source, a signals receiver, an inductance coil (connected to the direct current source) and a control unit; into the latter one introduces at least one additional inductance coil connected parallel to the base one; the coils are connected to the differential amplifier input via a commutator.
EFFECT: invention ensures the possibility to create a small-scale installation for research allowing to determine the properties of a major diameter core samples, enhancement of the measuring route total quality factor and interference level reduction, signal reading reliability end accuracy enhancement.
