Five very long, straight insulated wires are closely bound together to form a small cable. Currents carried by the wires are: I_1=20A, I_2=-6A, I_3=12A, I_4=-7A, I_5=18A . (Negative currents are opposite in direction to the positve.) The magnetic field induction at a distance of 10cm from the cable is (current enters at A and leaves at B and C as shown)
