A rectangular loop of wire is placed in the 
-plane with its side of length 
parallel to the 
-axis and the side of length 
parallel to the 
-axis. It is moving in the positive 
-direction with the speed 
. A magnetic field exists in the space with its direction parallel to the 
-axis. The field decreases by 
along the positive 
-axis and increases in time by 
. The induced emf in the wire is
