Abstract

The mechanism of formation of a nutation line in a flowing liquid is considered. New ones have been developed equations of motion of the longitudinal and transverse components of the magnetization vector in the nutation coil, which take into account the inhomogeneity of the magnetic field ΔH_0 in the zone of influence of the radio frequency field H_1 on the flowing liquid. The equations also take into account the nature of the change in the value of the magnetic field inhomogeneity ΔH_0 when the fluid moves along the nutation coil. The results of experimental studies of the shape of the nutation line are presented. Theoretical calculations are compared with experimental data.
