Question

Two long straight wires are perpendicular to the page and separated by a distance d₁ = 0.850 cm. Wire 1 carries a current 8.40 A into the page. The magnetic field at point P, a distance d₂ = 4.45 cm below wire 2, is zero (0 T). What must be the current in wire 2?

8.40 A, out of the page.
7.05 A, out of the page.
0 A, there is no current.
44.0 A, into the page.
