Magnetic Effects of Current and Magnetism Part 2

Two long parallel wires carrying currents 8A and 15A in opposite directions are placed at a distance of 7‌cm from each other. A point P is at equidistant from both the wires such that the lines joining the point P to the wires are perpendicular to each other. The magnitude of magnetic field at P is ______ ×10−6T. (Given : √2=1.4)
