Description
The non-zero value of the reactor mixing angle $\theta_{13}$ has ruled out the possibility of $\mu$-$\tau$ symmetry in neutrino mass matrix, there can still be a magic symmetry in neutrino mass matrix. In this context, we explore several classes of two texture zeros such as Class $A$, Class $B$, Class $C$ and Class $D$ in magic neutrino mass matrix and obtain the relation between one unknown phase $\phi$ and two known parameters: $\Delta {m_{23}^2}$ and ratio of two mass square difference (r=$\Delta {m_{12}^2}$/$\Delta {m_{23}^2}$). We also analyses the variation of unknown phase $\phi$ with respect to mixing angles ($\theta_{13}$ and $\theta_{23}$), Dirac CP violating phase $\delta$, Majorana phases ($\alpha$ and $\beta$) and Jarlskog invariant CP violation parameter J and their experimental validity.
