shows a  circular wheel of radius 10.0 cm whose upper half, shown dark in the figure, is made of iron and the lower half of wood. The two junctions are joinded by an iron rod. A uniform magnetic field B of magnitdue 2.00X 10^(-4) T exists in the space above  the central line as  suggested by the figure. The wheel is set  into pure rolling on the horizontal surface. The wheel is set into pure rolling on the horizontal surface. If it takes 2.00 seconds for the iron part  to come down and the wooden part to go up, find the average emf induced during this period.
