In the given circuit below inductance values of $\displaystyle L_1, L_2$ and $\displaystyle L_3$ are same. The magnetic energy stored in the entire circuit is $\displaystyle \left(U_t\right)$ and that stored in the $\displaystyle \mathrm{L}_2$ inductor is $\displaystyle \left(U_l\right) . U_t / U_l$ is $\displaystyle \_\_\_\_$. (Ignore the mutual inductance if any)
