*.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?

62 O In Fig. 28-51a, two concentric coils, lying in the same
plane, carry currents in opposite directions. The current in the
larger coil 1 is fixed. Current iz in coil 2 can be varied. Figure 28-51b
gives the net magnetic moment of the two-coil system as a function
of iz. The vertical axis scale is set by Hnet, = 2.0 x 10-5A m², and
the horizontal axis scale is set by iz, = 10.0 mA. If the current in
coil 2 is then reversed, what is the magnitude of the net magnetic
moment of the two-coil system when iz = 7.0 mA?

Wire 2, shown in cross section, is long, straight, and per- pendicular to the plane of the figure. Its distance from the center of the arc is equal to the radius R of the arc, and it carries a current iz that can be varied. The two currents set up a net magnetic field B at the center of the arc.

Suppose that the vertical wire has end points at rд = −2 cos 60° î+ Rsin 60° ĵ and rß = −R cos 60° î - R sin 60° ĵ, with the positive current I flowing from point A to point B. On the other hand, the circular wire has a radius R centered at the origin and passes through points A, B, and C, with the position rc = Rî. If a positive current I flows along the wire, passing through the points A, B, C, and back to A, use Biot-Savart law to find the resulting magnetic field at point D, where rp = zk.

A loop of wire in the x-y plane is in this field (the magnetic field is perpendicular to this loop); it has a total resistance R independent of the radius r of the loop.
