There is a lot going on inside atomic nuclei. Protons and neutrons are whizzing around and interacting with each other. The movement of the nuclear particles and their intrinsic angular momentum induce magnetic moments. Together, this can make atomic nuclei tiny magnets. There is a lot going on inside atomic nuclei.
