Research of nutation kinetic in a strong inhomogeneous field

The necessity of describing the mechanism for the formation of a nutation line in a flowing liquid is substantiated. The shortcomings that are inherent in the equations used to describe the motion of the longitudinal and transverse components of the magnetization vector in a nutation coil with a flowing liquid are noted. New equations of motion of the longitudinal and transverse components of the magnetization vector in a nutation coil with a flowing liquid are developed, in which the inhomogeneity of the magnetic $\Delta B_0$ in the zone of action of the radio-frequency field H1 on the flowing liquid is taken into account. The developed equations take into account the nature of the change in the value of the inhomogeneity of the magnetic field $\Delta B_0$ when the magnetized liquid moves along the length of the nutation coil. Nutation lines were calculated for various parameters of the magnetic field and flowing fluid. The results of experimental studies of the shape of the nutation line are presented. Theoretical calculations are compared with experimental data.
