Carousel illustration

Place the magnetometer at the carousel’s center to represent the nucleus sensing its magnetic environment.
– Spinning the carousel with a child holding an electrically charged ball mimics the orbital field created by moving electrons.
– A child holding a bar magnet illustrates the spin-dipolar field common in p- or d- orbitals.
– Moving that bar magnet directly over the magnetometer simulates the fermi contact term, representing s-electrons that overlap with the nucleus.
