Two long, straight wires carry equal currents in opposite directions as shown in figure. The separation between the wires is $5.0\text{ cm}$. The magnitude of the magnetic field at a point P midway between the wires is $\underline{\quad}\ \mu\text{T}$ . (Given : $\mu_0 = 4\pi \times 10^{-7}\text{ T m A}^{-1}$)
