As shown in figure Q - 4 both coil and bar magnet moves in the same direction. Your friend is arguing that there is no change in flux. Do you agree with his statement ? If not, what doubts do you have ? Frame questions about the doubts you have regarding change in flux.
No. I don’t agree with my friend.
- If both coil and bar magnet moves in the same direction what will be the relative notion ?
- Without relative motion of coil and bar magnet how can we get change in magnetic flux ?
- How can we get induced emf without, change in magnetic flux ?
- Is the coil moving with same velocity of that of the magnet ?
