WebThe polarization is a product of the gyromagnetic ratio (γ) of the nuclei and the applied magnetic field strength over the temperature. A typical polarization of 1H nuclei is in the order of 0.001% to 0.005% at 3 T, which gives a relatively poor signal-to-noise ratio. WebGyromagnetic ratio: Gyromagnetic ratio is defined as $\dfrac{m}{L}=\dfrac{e}{2{{m}_{e}}}$. When we put the value of charge of electron and mass of electron in the above equation. ... Hence, we can also say that the Gyromagnetic ratio also equals to magnetic moment per unit angular momentum.
