In the Figure, a Rectangular Current Loop Is Carrying Current $1.7 \times 10 ^ { - 6 } \mathrm {~N}$

Short Answer

In the figure, a rectangular current loop is carrying current I₁ = 7.0 A, in the direction indicated, near a long wire carrying a current I_w. The long wire is parallel to the sides of the rectangle. The rectangle loop has length 0.80 m and its sides are 0.10 m and 0.70 m from the wire. If the net force on the loop is to have magnitude $1.7 \times 10 ^ { - 6 } \mathrm {~N}$ and is to be directed towards the wire, what must be the magnitude and direction (from top to bottom or from bottom to top in the sketch)of the current I_w in the wire?
