Long Answer Questions 1. B A wire loop of radius r = 10 cm is rotating at a constant rate in a region with uniform magnetic field B = 4 T. The figure at right shows the loop at two instants, t, and t2. a) Rank the magnitude of the external flux at the two instants. If the external flux is equal to zero at either instant state so explicitly. Explain your reasoning. b) Rank the magnitude of the induced flux at the two instants. If the induced flux is equal to zero at either instant state so explicitly. Explain your reasoning. c) If the difference in time between the two instants is t2 - t1 = 5 seconds, what is the average induced emf ε in the loop between instants t, and tz? Show your work and explain your reasoning. d) How would your answer to part c change if the loop were rotating twice as quickly? Explain your reasoning.
