Two vertically hanging wires have a fixed horizontal sep 85 cm, and they carry upward c rents of i1 and i2, respectively. It is determined that wh i1 = 3.5 A, there is a sweet spot located a perpendicular d tance ri = 24 cm away from the first wire (and in the pla of the two wires) where the net magnetic field is precise ration distance of d

Transcribed Image Text:Two vertically hanging wires have a fixed horizontal sepa-
85 cm, and they carry upward cur-
rents of i and i2, respectively. It is determined that when
i1 = 3.5 A, there is a sweet spot located a perpendicular dis-
24 cm away from the first wire (and in the plane
of the two wires) where the net magnetic field is precisely
zero. Under these conditions, what current iz must be flow-
ration distance of d
tance ri =
ing through the other wire? Make sure that you indicate the
direction of the magnetic field from each wire in your repre-
sentation. It may be helpful to make two different drawings
from different perspectives: (1) the wires lie in the plane of the
page and point upward, and (2) the wires are perpendicular
to the page and point directly at you.
