This paper proposed the new method of the quantitative analysis about the behavior of a macroscopic magnetization vector in inhomogeneous magnetic fields, in which the static magnetic field and the RF magnetic field are not orthogonal to each other, and described the effectiveness. In recent years, unilateral NMR systems were developed as substitute for general NMR systems. Those systems are capable of measuring objects which are larger compared with the probe, because the measured area is not contained between magnets. Moreover, it is also possible to move the system, and miniaturization of the system provides a lot of advantage. However, a problem with those NMR systems is that, as the entire system becomes compact, the signal detecting area also becomes narrower. With such situation as background, we are studying a unilateral NMR system capable of detecting signals in wide areas for the purpose of achieving miniaturization of the system. In this paper, we analyzed behaviors of macroscopic magnetization vector in inhomogeneous magnetic fields by means of computer simulation. This analysis is useful in designing a unilateral NMR system, because it can be applied to NMR system of any desired shape.
