Clever farmers with power lines crossing their land have been known to steal power by stringing wire near the power line and making use of the induced current. At least one such crime went to court and resulted in a conviction?despite the defense?s claim that the defendant didn?t touch the lines. Figure 27.42 shows a possible crime scene, with a rectangular wire loop mounted in a vertical plane beneath a power line. The power line carries a current of 104 A, alternating sinusoidally at 60 Hz.

If the loop?s vertical dimension were doubled by extending it toward the power line (dashed line in Fig. 27.42), the induced emf woulda. double.b. quadruple.c. more than double but not quadruple.d. increase but not quite double.
