A regular polygon of $\displaystyle 6$ sides is formed by bending a wire of length $\displaystyle 4 \pi$ meter. If an electric current of $\displaystyle 4 \pi \sqrt{3} \mathrm{~A}$ is flowing through the sides of the polygon, the magnetic field at the centre of the polygon would be $\displaystyle x \times 10^{-7} \mathrm{~T}$. The value of $\displaystyle x$ is $\displaystyle \_\_\_\_$.
