The necessity to develop a magnetometer for variations research in the mid-field magnetic strength with a relative error of 10^–6 is justified. A new design of nuclear magnetometer which uses maser with flowing liquid is proposed. The block diagram of the magnetometer is presented, and the principle of its operation is described in detail. Furthermore, the conditions of occurrence of maser generation are established. The measurement errors of magnetic field variations in the developed magnetometer design are calculated. The capabilities of the developed magnetometer are determined. Finally, the results of experimental investigations of various variations of magnetic fields are presented.
