A two-channel nutation magnetometer on the basis of the nuclear-magnetic resonance (NMR) is described. It allows measurements of the magnetic-field induction within a range of 0.06-8.29 mT with an inhomogeneity of a parts per thousand yen10(-2) cm(-1) in different compartments of a sea ship. The distance from the location of a device that records NMR signals to the point at which the magnetic induction is determined ranges from 1 to 69 m. The measurement error is 0.3% and the sensitivity is 10(-11) D cent/Hz(1/2).
