Inspired by the observation of the doubly charmed state

T_{c c}

and following theoretical studies on its spectroscopic parameters, we investigate its magnetic dipole moment, assigning it the quantum numbers

J^{P} = 1^{+}

, and both the compact diquark-antidiquark and molecular structures in the framework of the light cone QCD. We also calculate the magnetic dipole moment of the theoretically predicted singly charmed state,

Z_{V}^{+ +}

, with two units of electric charge and the quantum numbers

J^{P} = 1^{-}

in diquark-antidiquark picture. The numerical results are obtained as

μ_{T_{c c}^{+} - D i} = {0.66}_{- 0.23}^{+ 0.34} μ_{N}

μ_{T_{c c}^{+} - Mol} = {0.43}_{- 0.22}^{+ 0.23} μ_{N}

and

μ_{Z_{V}^{+ +}} = {3.35}_{- 0.73}^{+ 0.89} μ_{N}

. These results may be checked via other phenomenological approaches. The obtained results may be useful in exact determinations of the natures of these states.
