As Shown in the Figure,a Rectangular Current Loop Is Carrying

question 31

Short Answer

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 I_w?
(b)In which direction does I_w flow: from top to bottom or from bottom to top in the sketch?
