JEE Main 2025 — 22 January, Evening Shift — Question 62

Two long parallel wires $X$ and $Y$, separated by a distance of 6 cm , carry

currents of 5 A and 4 A , respectively, in opposite directions as shown in the figure.

Magnitude of the resultant magnetic field at point P at a distance of 4 cm from

wire Y is $\mathrm{x} \times 10^{-5} \mathrm{~T}$. The value of $x$ is $\qquad$ .

Take permeability of free space as $\mu_{0}=4 \pi \times 10^{-7}$ SI units.
