Force on parallel wires: As shown in the figure, a rectangular current loop is carrying current = 3.0 A, in the direction shown, and is located near a long wire carrying a current . 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 and is directed towards the wire. (a) What is the magnitude of the current I_w?
(b) In which direction does I_w flow: from top to bottom or from bottom to top in the sketch?
