Nuclear magnetization

Nuclear magnetization refers to the magnetic moment of an atomic nucleus. Magnetic resonance imaging (MRI) makes use of nuclear magnetic resonance (NMR). Some nuclei may have nuclear magnetization depending on their nuclear charge distribution and the spin of their protons and neutrons. Nuclei with an even number of protons and neutrons will have no magnetic force, but nuclei with an odd number of protons and neutrons may have magnetization. A nucleus with an odd number of protons or neutrons may behave like a bar magnet and have magnetic resonance. An example of this is hydrogen, which has a solitary proton. MRIs make use of hydrogen because of its potential for nuclear magnetization and relative abundance in the body in water and fat. The Bloch equations are a set of differential equations that describe the change in nuclear magnetization over time as a function of T1T2, and the magnetic field.
