A long straight wire carries a current I as shown in Fig. 21-55. A small loop of wire rests in the plane of the page. Which of the following will not induce a current in the loop? (a) Increasing the current in the straight wire. (b) Moving the loop in a direction parallel to the wire. (c) Rotating the loop so that it becomes perpendicular to the plane of the page. (d) Moving the loop farther from the wire without rotating it. (e) Moving the loop farther from the wire while rotating it. FIGURE 21-55 MisConceptual Question 7.
