Features of the Formation of the Nutation Line in Nuclear Magnetic Resonance Magnetometers and Liquid Flow Meters

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.
