Similarity of force profile of a magnetic bound state and the strong nuclear interaction is shown where the right figure corresponds to the force keeping nucleons together. Coefficients (a, b) are dependent on magnet configurations and chosen here for obtaining similar curves. Nuclear strong force is incredibly strong and can keep nucleons together with a force exceeding one ton. The repusion force can be even larger and resists to a neutron star to collapse under its pressure which is calculated as 1000 MeV / fm³ ≈ 1.6 × 10³⁵ Pa.
