a circular coil is receding from a bar magnet wiyh same velocity as that of maget. Will an emf be induced
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...
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...
