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 20m above the ground and carries a 200 A current at a potential of 110 kV.

What is the magnetic field strength on the ground directly under such a transmission line?
