A power line carrying a sinusoidally varying current with frequency andpeak value runs at a height of 7.0 across a farmer's land (see thefigure). The farmer constructs a vertically oriented 2.0--high 15-turnrectangular wire coil below the power line. The farmer hopes to use theinduced voltage in this coil to power 130-Volt electrical equipment,which requires a sinusoidally varying voltage with frequency = 60 andpeak value = 190 .What should the length of the coil be?Would this be unethical?
