8. A bar magnet is dropped through a loop of copper wire as shown. Recall that ou magnet, magnetic field lines point away from a north pole and toward a south p positive direction of the induced current I in the loop is as shown by the arrows on the loop, the variation of I with time as the bar magnet falls through th by which of the following graphs (the time when the midpoint of the magnet passes t e loop is illustrated qualitatively the loop is indicated by the dashed line marked C)? A) 1 B) 2 E) 5 c) 3 D) 4 Back Front 5) 9 and 10. A rectangular loop of wire is pulled at a constant speed v to the left through a 20 cm region of uniform magnetic field. The magneti field is directed UP out of the diagram and has a magnitude of B 0.2T cm 9. The direction of the induced current flowing through the rectangular loop at the instant shown is: A) Clockwise. B) Counter clockwise C) No direction, it is zero. D) Clockwise in that part of the loop in the field and counter clockwise in the part of the loop not yet in the field. E) Counter clockwise in that part of the loop in the field and clockwise in that part of the loop not yet in the field. 10. If the speed of the loop at the instant shown is v (induced EMF) in the loop at that instant is: A) 100mv 2.5mis, then the B) 25mV E) 50mv C) 75my D) 500mv 20 2 11. The switch in the circuit on the left is closed at t-0 seconds. 0.1 seconds after the switch was closed, Is in 2H Amps is 150 V A. 7.Se B. C. DE
