(II) A power line carrying a sinusoidally varying current with frequency f = 60 Hz and peak value I 0 = 55 kA runs at a height of 7.0 m across a farmer’s land (Fig. 29–41). The farmer constructs a vertically oriented 2.0-m-high 10-turn rectangular wire coil below the power line. The farmer hopes to use the induced voltage in this coil to power 120-Volt electrical equipment, which requires a sinusoidally varying voltage with frequency f = 60 Hz and peak value V 0 = 170 V. What should the length ℓ of the coil be? Would this be unethical? FIGURE 29–41 Problem 16.
