magnetic field B = uoi/2pi R
B = (4* 3.14 e -7 * 1666)/(2*3.14 * 19)
B = 1.753 e -5 Tesla
B/Be = 1.753 e -5/5 e -5
B/Be = 35.06 %

option1, magnetic field lines are lesss danger than Earths magnetic field
There has been some concern in recent years over the possible health effects from magnetic fields...
Currents in DC transmission lines can be relatively high. Some people have expressed concern that the electromagnetic fields from such lines near their homes could cause health dangers. For a line with current 150 A and at a height of 8 m above the ground, what magnetic field does the line produce at ground level? Express your answer as a percent of the Earth's magnetic field, which is approximately 5
Please complete all steps and explain as thoroughly as possible
for the best possible rating.
Power lines produce both electric and magnetic fields. The interior of the human body is an electrical conductor, and as a result, electric fields are greatly reduced in magnitude within the body The electric fields inside the body from are much smaller than electric fields normally existing in the body However, magnetic fields are not reduced in the body. Earth's magnetic field, approximately 5 ×...
