Five very long insulated straight wires are bound together to form a small cable. Currentys carried by the wires are `I_1=20 A, I_2=-5A, I_3=10 A, I_4=+7 A and I_5=-12 A`. What is the magnetic induction at a perpendicular distance of 5 cm from the cable?

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)
