  We present the results of numerical calculations of magnetizability ($\chi$)
of the relativistic one-electron atoms with a pointlike, spinless and
motionless nuclei of charge $Ze$. Exploiting the analytical formula for $\chi$
recently derived by us [P. Stefa{\'n}ska, 2015], valid for an arbitrary
discrete energy eigenstate, we have found the values of the magnetizability for
the ground state and for the first and the second set of excited states (i.e.:
$2s_{1/2}$, $2p_{1/2}$, $2p_{3/2}$, $3s_{1/2}$, $3p_{1/2}$, $3p_{3/2}$,
$3d_{3/2}$, and $3d_{5/2}$) of the Dirac one-electron atom. The results for
ions with the atomic number $1 \leqslant Z \leqslant 137$ are given in 14
tables. The comparison of the numerical values of magnetizabilities for the
ground state and for each states belonging to the first set of excited states
of selected hydrogenlike ions, obtained with the use of two different values of
the fine-structure constant, i.e.: $\alpha^{-1}=137.035 999 139$ (CODATA 2014)
and $\alpha^{-1}=137.035 999 074$ (CODATA 2010), is also presented.
