A magnetic field passing through two identical coils decreases from a magnitude of B_ex to zero in the time interval Δt. The first coil has twice the number of turns as the second. (a) Compare the emfs induced in the coils. (b) How can you change the experiment so that the emfs produced in them are the same?
