2 A pair of coils of turns n and n2 are kept close together Current passing through the first is reducing at rate r and e m f 3 mV is developed across the other coil If the second coil carries current which is then reduced at the rate 2r the emf produced across the first coil will be 1 6n n mV 3 6 mV 2 602 mV n Vis 3 4 mV noo
