The current passing through a conducting loop in the form of equilateral triangle of side $\displaystyle 4 \sqrt{3} \mathrm{~cm}$ is $\displaystyle 2$ A. The magnetic field at its centroid is $\displaystyle \alpha \times 10^{-5} \mathrm{~T}$. The value of $\displaystyle \alpha$ is $\displaystyle \_\_\_\_$. (Given : $\displaystyle \mu_{\mathrm{o}}=4 \pi \times 10^{-7}$ SI units)
