We present an analytical study on acoustic magnetic resonance spectroscopy system for hydrogen nuclei in a viscous fluid medium. Magnetic flux density applied to a sample comprising of hydrogen nuclei results in alignment of the magnetic moments along the direction of magnetic field, which precess at Larmor frequency. An acoustic wave applied to the system leads to development of time varying shear forces which can be decomposed into a rotational and a strain component. The rotation of the nuclei around their axes exerts a time varying torque leading to an enhancement of the amplitude of oscillations eventually leading to the generation of radio frequency magnetic fields, which can be used for characterization of a given sample for diagnosis of physiological conditions.

我们目前对粘性流体介质中的氢核的声磁共振波谱系统进行分析研究。施加到包含氢核的样品的磁通密度会导致沿磁场方向的磁矩对齐，这在拉莫尔频率下是必需的。施加到系统上的声波导致时变剪切力的产生，该剪切力可以分解为旋转分量和应变分量。原子核绕其轴的旋转会施加随时间变化的转矩，从而导致振荡幅度增大，最终导致产生射频磁场，该磁场可用于表征给定样本以诊断生理状况。
