Although the evidence is weak, there has been concern in recent years over possible health effects from the magnetic fields generated by electric transmission lines. A typical high-voltage transmission line is 20 m above the ground and carries a 200 A current at a potential of 110 kVA. Estimate the magnetic field strength on the ground underneath such a line. B. What percentage of the earth’s magnetic field does this represent?
