A Nichrome (resistive) wire has the shape of two quarter-circles of radius a = 3.94 cm and b = 16.1 cm, connected by straight sections, which lie on the radii of the arcs, as shown. The wire carries conventional current I = 8.68 A in the direction shown. What is the net magnetic field, in microTesla, at Point C due to the wire loop. Use a negative sign if directed into the page and a positive sign if directed out of the page. Add your answer
