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 mm above the ground and carries a 200 A current at a potential of 110 kV.
Estimate the magnetic field strength on the ground underneath such a line.
What percentage of the earthâs magnetic field does this represent?
