    Six very long insulated copper wires are bound together to form a cable. The currents carried by the wires are i1=10i_1 = 10A, i2=−13i_2 = -13A, i3=10i_3 = 10A, i4=7i_4 = 7A, i5=−12i_5 = -12A and i6=18i_6 = 18 A. The magnetic induction at a perpendicular distance of 1010 cm from the cable is (μ0=4π×10−7(\mu_0 = 4\pi \times 10^{-7} SI units)
