(d). How much current is flowing through the surface area of the square loop

 

*5.27 In a given region of space, the vector magnetic potentiff is given by A = $5 cos Ty + 2(2 + sin rx) (Wb/m). (a) Determine B. (b) Use Eq. (5.66) to calculate the magnetic flux passing through a square loop with 0.25-m-long edges if the loop is in the x-y plane, its center is at the origin, and its edges are parallel to the x- and y-axes. (c) Calculate again using Eq. (5.67).
