Abstract
A mechanism of formation of the nutation line in a flowing liquid is discussed. New equations of motion of the longitudinal and transverse components of the magnetization vector in a nutation coil are derived, which take into account magnetic field inhomogeneity ΔН0 in the area of impact of RF field Н1 on the flowing fluid. In addition, the equations make allowance for the nature of magnetic field inhomogeneity change ΔН0 during motion of the liquid along the nutation coil. The results of experimental investigations of the nutation line shape are reported. The theoretical calculation is compared with experimental data.
