*.28 G0 In Fig. 30-51, a rectangular
loop of wire with length a = 2.2 cm, width b = 0.80 cm, and resist-
ance R = 0.40 mn is placed near an infinitely long wire carrying
current i = 4.7 A. The loop is then moved away from the wire at
constant speed v = 3.2 mm/s. When the center of the loop is at
distance r = 1.5b, what are (a) the magnitude of the magnetic flux
through the loop and (b) the current induced in the loop?

In Figure (a), a circular loop of wire is concentric with a solenoid and lies in a plane perpendicular to the solenoid's central axis.The loop
has radius 6.19 cm. The solenoid has radius 2.13 cm, consists of 8250 turns/m, and has a current isol varying with time t as given in
Figure (b), where the vertical axis scale is set by i, - 1.16 A and the horizontal axis scale is set by t, - 2.5 s. Figure (c) shows, as a function
of time, the energy Eth that is transferred to thermal energy of the loop; the vertical axis scale is set by E,- 102.6 nJ. What is the loop's
resistance?
