NOTE THAT PROBLEM 3 HAS JUST TWO SUBMISSIONS! ubs: 1/4 iewing: Last esponse iew: All esponses otes pts 1 1/1 1/1 1. [MI02 22.E.09.] A thick copper wire connected to a voltmeter surrounds a region of time-varying magnetic flux, an the voltmeter reads 9 volts. If instead of a single wire we use a coil of thick copper wire containing 19 turns, what does the voltmeter read? 171 [171] V ubs: 4/4 iewing: Last esponse iew: All esponses otes pts 1 2/2 2 1/1 3/3 2. [MI02 22.RQ.01.] 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 0.4 tesl am 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?
