Moving Charges And Magnetism

Two long parallel wires carrying currents \(8 \mathrm{~A}\) and \(15 \mathrm{~A}\) in opposite directions are placed at a distance of \(7 \mathrm{~cm}\) from each other. A point '\(\mathrm{P}\)' is at equidistant from both the wires such that the lines joining the point to the wires are perpendicular to each other. The magnitude of magnetic field at point '\(\mathrm{P}\)' is \((\sqrt{2}=1.4) ( \mu_0=4 \pi \times 10^{-7}\) SI units)
