A power line carrying a sinusoidally varying current with frequency of f= 60 Hz and peak value I = 55 kA runs at a height of 7 m across a farmer's land. The farmer constructs a vertically oriented 2 m high 10-turn rectangular wire coil below the powerline. The farmer hopes to use the induced voltage in this coil to power 120 V electrical equipment, which requires a sinusoidally varying voltage with frequency f= 60 Hz and peak value V = 170 V. What should the length l of the coil be?
