A typical power transmission line carries a current

Reference no: EM13651102

A typical power transmission line carries a current of 1000 A about 30.0 meters above the ground. The magnetic field generated at ground level by the current is a matter of concern to those who live nearby. (a) What is the strength of the field at ground level below one such wire? (b) The strength of the Earth's magnetic field is about 5×10−5 T at sea level in middle latitudes. How close would you have to be to the power line to experience from it a magnetic field of equal strength?
