How can I solve the following statement? You want to get an idea of the magnitude of magnetic fields produced by overhead power lines. You estimate that a transmission wire is about 20 m above the ground. The local power company tells you that the lines operate at 240 kV and provide a maximum power of 46 MW. Estimate the magnetic field you might experience walking under one such power line.
