24. Consider Plates I, II, and III shown below which are all made of metal. Which of the following statements are TRUE when each of them swings between the poles of a U-shaped magnet? " п III 1. Plate I will have the shortest duration of swinging between the poles of the U-shaped magnet. II. Plate I will produce the largest eddy currents on its surface in the presence of changing magnetic field. II. Plate Il will have the longest duration of swinging between the poles of the U-shaped magnet. IV. The gap in Plate III will prevent large eddy curents on its surface, which will cause it to swing the longest between the poles of the U-shaped magnet. V. The large amount of area absent in Plate II will prevent large eddy currents, which will cause it to swing the longest between the poles of the U-shaped magnet. A. I and IV B. I, Il and IV C. I, II and V D. II, II and V E. All of the above
