Calculate the magnetic field strength on the ground

Reference no: EM13538190

Although the evidence is weak, there has been concern in recent years over possible health effects from the magnetic fields generated by transmission lines. A typical high-voltage transmission line is 20 off the ground and carries a current of 200.

Part A Estimate the magnetic field strength on the ground underneath such a line. Express your answer using one significant figure.
