A coil ACD of N turns and radius R carries a current I Amp and is placed on a horizontal table.K is a very small horizontal conducting ring of radius r placed at a distance Y frm the centre of the coil vertically above the coil ACD .Find an expression for the EMF estabilished when the ring K is allowed to fall freely.Express the emf in terms of instantaneous speed v and height Y.
