Two long parallel wires carrying currents $\displaystyle 8$ A and $\displaystyle 15$ A in opposite directions are placed at a distance of $\displaystyle 7$ cm from each other. A point $\displaystyle P$ is at equidistant from both the wires such that the lines joining the point $\displaystyle P$ to the wires are perpendicular to each other. The magnitude of magnetic field at $\displaystyle P$ is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{-6} \mathrm{~T}$. (Given : $\displaystyle \sqrt{2}=1.4$ )
