Five very long, straight insulated wires are closely bound together to form a small cable. Currents carried by the wires are: I1=20A,I2=−6A,I3=12A,I4=−7A,I5=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)
