The north pole of a magnet is brough down along the axis of a horizontal circular coil (figure) As a result the flux through the coil changes from `0.4 Weber` to `0.9 Weber` in an interval of half of a second.Find the average `emf` induced during this period.Is the induced current clockwise and anticlockwise as you look into the coil from the side of the magnet?
