s. Consider a loop of wire suspended from a string and oscillating back and forth as the bob in a pendulum. The diagram below shows the loop's position at several different moments in time. The dashed box indicates a region of space in which there is a magnetic field pointing out of the page. r=0 a) At what moment or moments in the diagram does the wire loop experience an induced emf? Explain your reasoning. Consider a loop of wire oscillating up and down at the end of a spring. The figure below shows the same loop at different moments in time. I=0 rm1 =2 1m3 14 1-3 1-6 Ollllll 0000000 Dellele oooooo ooooooo b) The dashed region of constant magnetic field will cause the loop to experience an induced emf at some moments in time but not at other moments if the direction of the magnetic field is (circle all correct choices): i) toward the top of the page ii) toward the bottom of the page iii) toward the right side of the page iv) into the page v) out of the page
d) Two identical metal discs are attached to identical strings and pulled back to the same position before being released. The first pendulum starts its swing outside the magnetic field and the second pendulum is inside the magnetic field for the entirety of its swing (the arrows indicate how far each pendulum swings). Which pendulum will oscillate back and forth for the longest time before coming to a stop? Explain your reasoning. t=0
