1. (15%) A magnetic field is given in the xz-plane by6131b7620005a.jpg, Wb/m2. Consider a regid square loop situated in the xz-plane with its vertices at (x, 0, 1), (x+1,0, 1), (x+1,0, 2), and (x, 0, 2). Find the emf induced around the loop in the sense defined by connecting the above points in succession.
