The $g$ factors of the $2_1^{+}$ levels of ${}_{}{}^{92}{}_{}{}^{}\mathrm{Zr}$ and ${}_{}{}^{94}{}_{}{}^{}\mathrm{Zr}$ have been measured using the dynamic magnetic field which acts on fast ions traversing a thin magnetized iron foil. The results obtained are $g({}_{}{}^{92}{}_{}{}^{}\mathrm{Zr}, 2_1^{+})=-0.03\mathrm{}\pm 0.05$ and $g({}_{}{}^{94}{}_{}{}^{}\mathrm{Zr}, 2_1^{+})=-0.26\mathrm{}\pm 0.06$. The present results indicate sizable admixture of components other than $d_{\frac{5}{2}}$ neutrons in the wave functions of these levels.
