A simple expression for the intrinsic form factor of magic nuclei in the lowest order approximation of the hyperspherical-coordinate method is derived, discussed, and applied to ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ and ${}_{}{}^4{}_{}{}^{}\mathrm{He}$. A good agreement with experimental values for $q^2\lesssim 8$ ${\mathrm{fm}}^{-2\mathrm{}}$ and the appearance of a dip in the form factor of ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ are noticed.
