Physics Question from JEE Main 2025 · 22 January, Shift 2

Two long parallel wires X and Y, separated by a distance of $6 \, \text{cm}$, carry currents of $5 \, \text{A}$ and $4 \, \text{A}$, respectively, in opposite directions as shown in the figure. The magnitude of the resultant magnetic field at point P, at a distance of $4 \, \text{cm}$ from wire Y, is $x \times 10^{-5} \, \text{T}$. The value of $x$ is _____. (Take permeability of free space as $\mu_0 = 4\pi \times 10^{-7}$ SI units.)
