Transcribed Image Text:

A power line carrying a sinusoidally varying current with frequency f = 60Hz and peak value Io = 55kA runs at a height of 7.0 m across a farmer's land (see the figure). 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 130-Volt electrical equipment, which requires a sinusoidally varying voltage with frequency f = 60Hz and peak value Vo = 190 V (Figure 1) Figure lo = 55 KA f = 60 Hz Coil 7.0 m + 2.0 m < 1 of 1 Part A What should the length I of the coil be?
