Parallel Wires: 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 Iw. 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 × 10-6 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 Iw in the wire? (?0 = 4? × 10-7 T ? m/A)
What will be an ideal response?
0.18 A, from bottom to top
