Abstract
The present work is concerned with theoretical and experimental investigations of the parameters of a free nuclear induction signal when the direction of the exciting field changes along the motion trajectory of a liquid under study. The nuclear magnetic resonance (NMR) experiments are carried out in the geomagnetic field by use of special sensors, namely, a toroid and sensors having linear or cycle displacement of frame coils. The main theoretical approach is based on the usage of the signal of the free induction decay in the integral form derived from the reciprocity principle. The obtained results allowed us to define the physical origin of the NMR frequency shift and to propose a general analytic expression of this shift for the three sensors. The condition of the equality of the sample or sensor motion is proposed also.
