Physics - Magnetism Question with Solution | TestHub

Two long parallel wires $X$ and $Y$, separated by a distance of 6 cm , carry currents of 5A and 4A, 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 $x\times 10^{-5}\mathrm{T}$. The value of $x$ is__________ . Take permeability of free space as ${\mu }_0=4\pi \times 10^{-7}\mathrm{SI}$ units.
