As shown in the figure, a rectangular current loop

(1) As shown in the figure, a rectangular current loop is carrying current I = 3.0 A, in the direction shown, and is located near a long wire carrying a current I. 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 x 10-6 N and is directed towards the wire. (H0= 47 x 10-7 T.m/A) I 0.10 m 1 0.70 m 0.80 m (a) What is the magnitude of the current Iw? (b) In which direction does lw flow: from top to bottom or from bottom to top in the sketch?
