The wire loop in Figure la) is subjected, in turn, to six uniform magnetic elds, each directed parallel to the z axis. Figure (la) gives the 2 components B2 of the elds versus time t. (Plots 1 and 3 are parallel; so are plots 4 and 6.) Rank the six plots according to the emf induced in the loop, greatest clockwise emf rst, greatest counterclockwise emf last. If multiple choices rank equally, use the same rank for each, then exclude the intermediate ranking (i.e. if objects A, B, and C must be ranked, and A and B must both be ranked rst, the ranking would be AzGreatest, BzGreatest, CzThird greatest). If all choices rank equally, rank each as 'Greatest'.

A circular conducting loop of area 10 X 10'4 m2 lies in the eld, in the plane of the page. The amount of charge q passing pointA on the loop is given in Figure (c) as a function of t, with the vertical axis scale set by qs = 8.9 mC and the horizontal axis scale again set by tS = 5.6 5.

It depends on the inductance. It depends on the inverse of the inductance. It depends on the self-induced emf. 0 It depends on the inverse of the seifinduced emf. ' X Youranswerisincorrect. An inductance i. and a resistance R are connected in series to an ideal battery. A switch in the circuit is closed at time t = O, at which time the current is zero. The energy stored in the inductor is a maximum: just after the switch is closed at the time t = L/R after the switch is closed 0 at the time t = L/R2 after the switch is closed at the time t = 2L/R after the switch is closed a long time after the switch is closed
