Resultant Magnetic Field of Parallel Wires
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 × 10–5 T. The value of x is ________. Take permeability of free space as μ0 = 4π × 10–7 SI units.
