We can consider the carrousel as being equivalent to a atomic crystal structure which has cubic symmetry. Using the magnetometer we can then effectively measure the fermi contact contribution. By then placing the child on the carrousel, we remove the chemical symmetry and thus also the cubic symmetry. By then placing the magnet somewhere on the carrousel we add the spin dipolar contribution to our hyperfine field. Using our knowledge of the fermi contact contribution we can then also determine the spin dipolar contribution. Afterwards we take the magnet away and replace it by an electrically charged ball. By then letting the carrousel rotate around its axis, we can measure orbital contribution.
