In a given region of space, the vector magnetic potential is given by A =x5cosy + z(2+sinx) (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).
