Question
In the figure below, a semicircular conductor of radius R = 0.280 m is rotated about the axis AC at a constant rate of 200rev/min. A uniform magnetic field of magnitude 1.38 T fills the entire region below the axis and is directed out of the page.
In the figure below, a semicircular conductor of radius R = 0.280 m is rotated about the axis AC at a constant rate of 200rev/min. A uniform magnetic field of magnitude 1.38 T fills the entire region below the axis and is directed out of the page. Calculate the maximum value of the emf induced between the ends of the conductor. What is the value of the average induced emf for each complete rotation? How would your answers to parts (a) and (b) change if the magnetic field were allowed to extend a distance Rabove the axis of rotation? (Select all that apply.) The value in part (a) would increase.The value in part (a) would remain the same.The value in part (a) would decrease.The value in part (b) would increase.The value in part (b) would remain the same.The value in part (b) would decrease. Sketch the emf versus time when the field is as drawn in the figure. Sketch the emf versus time when the field is extended as described in part (c).Explanation / Answer
