Transcribed Image Text:Let us apply the concepts of motional emf and Lenz's law
to a slide-wire generator. Suppose the length L of the
slide-wire rod in (Figure 1) is 0.10 m, its speed v is
2.5 m/s, the total resistance of the loop is 0.030 N,and
B is 0.60 T. Find the emf, E, the induced current, the
force acting on the rod, and the mechanical power
needed to keep the rod moving at constant speed.
