Magnetization & Magnetic Intensity | Magnetic Properties

Magnetization, also termed magnetic polarization, is a vector quantity that measures the density of permanent or induced dipole moment in a given magnetic material. As we know, magnetization results from the magnetic moment, which results from the motion of electrons in the atoms or the spin of electrons or the nuclei.

What NMRs Actually Tell Us

The higher-energy state with the proton aligned against the external magnetic field is called the beta -spin (#beta#-spin) state. In the absence of an external magnetic field, proton magnetic moments have random orientations. When an external magnetic field is applied, each proton in a sample assumes the #alpha# or #beta# state.
