Figure P31.44 (page 964) is a graph of the induced emf

Chapter 31, Problem 44

(choose chapter or problem)

Figure P31.44 (page 964) is a graph of the induced emf versus time for a coil of N turns rotating with angular speed v in a uniform magnetic field directed perpendicular to the coils axis of rotation. What If? Copy this sketch (on a larger scale) and on the same set of axes show the graph of emf versus t (a) if the number of turns in the coil is doubled, (b) if instead the angular speed is doubled, and (c) if the angular speed is doubled while the number of turns in the coil is halved.
