A pair of stationary and infinitely long bent wires are placed in the x -y plane as shown in the figure. The two wires carry currents of 4 A and 9 A respectively. If the segments D and A are along the x-axis and the segments C and F are parallel to y axissuch that OB = 2cm and OE = 3 cm, then the magnitude of the magnetic induction at the origin 'O' is
(µ0 = 4π × 10−7Hm−1)
