case1)


if bar magnet is moving in opposite direction to the motion of coil then relative motion exists ,


relative velocity = v+v=2v


 


case2)


but if both are moving in same direction then there is no relative otion


relative velocity = v-v=0


condition for induced emf is relative motion bw coil and magnet


 so in case 1 emf is induced but in case 2 emf is zero...
