PPT Slide Slide 1 of 33 Imagine, if you will, a world without magnets. Without magnets, your car s starter motor would not engage and disengage.
Conventional magnetism is mostly due to the electrons that orbit atomic nuclei.
Nuclear magnets play a more modern, but arguably equally important role in our lives. For example, NMR and MRI, so crucial to modern medicine and pharmacology are based on nuclear magnetism. Atomic clocks that are the basis of the Global Positioning System rely on the interaction of electron and nuclear magnets. And nuclear magnetism provides a marvelously useful experimental handle for study of the interactions of elementary particles in the very early Universe. These interactions are believed to have resulted in the dominance of matter vs antimatter in the Universe.
