Problem 3 (15 points total]: a) lathe Faraday's Law lab (see gure), you dropped a small: cylindrical bar magnet through a coil and measured the flux and the induced emf in the coil. Consider a hypothetical Z | new cylindrical bar magnet= measuring 2 cm in diameter, - but of unknown field strength and with unmarked poles. Using the Faraday's Law experimental setup with a coil of V 200D turns, you produce the following graphs of induced emf and ux by dropping this new magnet through the coil. El. ?E| Initu oodHMP'W] D.6? Time (5] Assuming counterclockwise (as seen from above) indicates positive current in the coil: did the north or south end ofbar magnet drop rst into the coil? Please explain. ' As in the actual lab, you notice that the magnitudes of the peaks inthe induced emf graph are slightly di'erent. Please explain why
