Currents in dc transmission lines can be 100 A orhigher. Some people are concerned that theelectromagnetic fields from such lines near theirhomes could pose health dangers.For a line that has current 170 A and a height of 8.0 m above the ground, what magnetic field does the lineproduce at ground level? Express your answer in teslas.Express your answer in teslas.να ΑΣΦ?B =TPart BWhat magnetic field does the line produce at ground level as a percent of the earth's magnetic field, which is0.50 G.Express your answer as a percentage.B%BE國 Part CIs this value of magnetic field cause for worry?Yes. Since this field is much greater than the earth's magnetic field, it would be expected to havemore effect than the earth's field.Yes. Since this field does not differ a lot from the earth's magnetic field, it would be expected to havealmost the same effect as the earth's field.No. Since this field does not differ a lot from the earth's magnetic field, it would be expected to havealmost 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 haveless effect than the earth's field.
