A current of $\displaystyle 30$ A each flows in opposite directions in two conducting wires, placed parallel to each other at a distance of $\displaystyle 8$ cm . The magnetic field at the mid point between the two wires is $\displaystyle \_\_\_\_$ $\displaystyle \mu \mathrm{T}$. $$\left(\frac{\mu_{\mathrm{o}}}{4 \pi}=10^{-7} \mathrm{~N} / \mathrm{A}^2\right) $$
