PPT-NMR Spectroscopy Electron has a spin and that spinning creates and associated magnetic

Electron can behave like a tiny bar magnet Atomic nucleus can spin and behave as a tiny bar magnet These spinning nuclei generate tiny magnetic fields Any nucleus will spin odd mass or odd atomic number. electromagnons. excitation in a . hexaferrite.
