Magnetic Effects of Current and Magnetism Part 3

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 x×10−5 T. The value of x is _____ Take permeability of free space as µ0=4π×10−7‌SI units.
