A power line carrying a sinusoidally varying current with frequency f=60Hz and peak value I0=55kA runs at a height of 7.0m across a farmer’s land (see the figure). The farmer constructs a vertically oriented 2.0m–high 11-turn rectangular wire coil below the power line. The farmer hopes to use the induced voltage in this coil to power 110-Volt electrical equipment, which requires a sinusoidally varying voltage with frequency f= 60 and peak value Vo= 150V .What should the length l of the coil be?
