Currents in dc transmission lines can be 100 A or higher. Some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. For a line that has current 130 A and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? Express your answer in t Express your answer in teslas. [U] ΑΣΦ B= Submit Part B BE = Submit 3 Part C Request Answer What magnetic field does the line produce at ground level as a percent of the earth's magnetic field, which is 0.50 G. Express your answer as a percentage. ΕΠΙΑΣΦΑ 3 → C Request Answer → C P Is this value of magnetic field cause for worry? ? T ? % No. Since this field does not differ a lot from the earth's magnetic field, it would be expected to have almost the same effect as the earth's field. Yes. Since this field does not differ a lot from the earth's magnetic field, it would be expected to have almost the same effect as the earth's field. No. Since this field is much smaller than the earth's magnetic field, it would be expected to have less effect than the earth's field. Yes. Since this field is much greater than the earth's magnetic field, it would be expected to have more effect than the earth's field.
