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...
