22 turns, what does the voltmeter read? 220 220 V 2. 3/3 points All Submissions Notes Question: MI2 22.RQ.20 Question part Points Submissions 1 2 2 1 2/3 1/1 Total 3/3 The north pole of a bar magnet points toward a thin circular coil of wire containing 46 turns (Figure 22.52). The magnet is moved away from the coil, so that the flux through one turn inside the coil decreases by 0.5 tesla · m 2 in 0.3 seconds. What is the average emf induced in the coil during this time interval? Viewed from the right side (opposite the bar magnet), does the induced current run clockwise or counterclockwise? 76.67
