(I) How much current is flowing in a wire 4.80 m long if themaximum force on it is 0.625 N when placed in a uniform0.0800-T field?
Suspending Suspending a wire with a current. A horizontal wire carries a current I1 = 80 A dc. A second parallel wire 20 cm below it (Fig. 28-7) must carry how much current I2 so that it doesn't fall due to gravity? The lower wire has a mass of 0.12 g per meter of length.
