As shown in the figure, a rectangular current loop is carrying current I₁ = 3.0 A, in the direction shown, and is located 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, as shown. We measure that the net force on the rectangular loop is 4.9 × 10^-6 N and is directed towards the wire. (μ0 = 4π × 10^-7 T ∙ m/A)
(a) What is the magnitude of the current Iw?
(b) In which direction does Iw flow: from top to bottom or from bottom to top in the sketch?

As shown in the figure, a rectangular current loop is carrying current I<sub>1</sub> = 3.0 A, in the direction shown, and is located near a long wire carrying a current I<sub>w</sub>. 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, as shown. We measure that the net force on the rectangular loop is 4.9 × 10<sup>-6</sup> N and is directed towards the wire. (μ0 = 4π × 10<sup>-7</sup> T ∙ m/A) (a) What is the magnitude of the current Iw? (b) In which direction does Iw flow: from top to bottom or from bottom to top in the sketch?
