A computational algorithm is developed for the magnetic-dipole constant of the hyperfine structure of atomic spectra, which takes into account the distribution of the magnetic moment in the nuclear volume both in the relativistic and in the nonrelativistic formulation. A significant difference between the nonrelativistic approximation, and the pointlike nucleus approximation is the presence of a nonzero contact hyperfine interaction for electrons with nonzero orbital angular momentum in the former case. The procedure is tested in the computation of the Bohr-Weisskopf correction for hydrogen-like spectra.
