1. [MI02 22.E.09.] 1/1 points | 1/4 submissions Last Response | Show Details All Responses Notes A thick copper wire connected to a voltmeter surrounds a region of time-varying magnetic flux, and the voltmeter reads 12 volts. If instead of a single wire we use a coil of thick copper wire containing 23 turns, what does the voltmeter read? 276 276 V 2. [MI02 22.RQ.01.] 3/3 points | 1/4 submissions Last Response | Show Details All Responses Notes The north pole of a bar magnet points toward a thin circular coil of wire containing 50 turns (Figure 22.52). The magnet is moved away from the coil, so that the flux through one turn inside the coil decreases by 0.1 tesla · m 2 in 0.2 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? 25 25 volts (o) (o) counterclockwise (_) (_) clockwise Figure 22.52 3. 2/2 points | 2/4 submissions Last Response | Show Details All Responses Notes A rectangular loop A very long, tightly-wound solenoid has a circular cross section of radius
