FIELD: physics.
SUBSTANCE: invention relates to electromagnets for measurement of nuclear magnetic resonance in weak field, in particular for determination of water in a sample. Electromagnet comprises yoke (1), having volume (4), and conductive wire (7) wound around yoke (1). Magnet includes at least two circular groove (5), having two walls parallel to each other and perpendicular to longitudinal axis of frame, at least, two beams (7) wires, each of which contains at least one substack (7a, 7b). At least one of walls (6) separates two circular grooves (5). Overlapping wire (10), connecting beams so that fraction of overlapping wires (10) of adjacent beams in full axially directed current are suppressed on average by wire current reverse current so that their portion in resultant magnetic field in volume of sample is minimised.
EFFECT: technical result is improvement of uniformity of magnetic field in volume with reduced dimensions.
