3. 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. t=0 t = 1 t = 2 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. t = 0 t = 1 t = 2 t = 3 t = 4 t = 5 t = 6 Ollllll Delllll Ceeeell I oooooo Delllll Olllll B 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 Explain your reasoning.
