The currents into the page are i1 = 2.00 A, i3 = 0.250 A, i4 = 4.00 A, and i5 = 2.00 A; the current out of the page is i2 = 4.00 A.

The use of superconductors has been proposed for power transmission lines. A single coaxial cable (Fig. P23.73) could carry a power of 1.00 103 MW (the output of a large power plant) at 200 kV, DC, over a distance of 1.00 103 km without loss. An inner wire of radius a = 2.00 cm, made from the superconductor Nb3Sn, carries the current I in one direction. A surrounding superconducting cylinder of radius b = 5.00 cm would carry the return current I.

Wire 2, shown in cross section, is long, straight, and per- pendicular to the plane of the figure. Its distance from the center of the arc is equal to the radius R of the arc, and it carries a current iz that can be varied. The two currents set up a net magnetic field B at the center of the arc.
