MC __________ Prob 9 __________ Raw Total __________ Percentage __________% MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question Figure 29.9 1) In Fig. 29.9, a bar magnet moves away from the solenoid. The induced current through the resistor R is: A) zero B) from a to b C) from b to a 1) 2) A small square coil is located inside an ideal solenoid at the center with its plane oriented perpendicular to the axis of the solenoid. The resistance of this coil is 2.00 Ω and each side is 4.00 cm long. The solenoid has 125 windings per centimeter of length. If the current in the solenoid is increasing at a constant rate of 1.50 A/s, the current in the square coil is: A) decreasing at 1.50 A/s B) initially equal at 18.8 μA but is increasing C) increasing at 1.50 A/s D) steady at 18.8 μA E) zero 2) A-1
