The north pole of a magnet is brought do...

The north pole of a magnet is brought 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 or anticlockwise as you look into the coil from the side of the magnet ?
