What is the magnetic field strength on the ground

Reference no: EM13706343

Solve the all parts of given question:

Question: 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 15m above the ground and carries a 200 Amp current at a potential of 110 kV.

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

Part B: What percentage is this of the earth's magnetic field of 50T?

I need help to solve the above question and express your answer to two significant figures and include the appropriate units.
