Constants
A very long, straight solenoid with a diameter of 3.00 cm is wound with 40 turns of wire per centimeter, and the windings carry a current of 0.245 A . A second coil having N turns and a larger diameter is slipped over the solenoid so that the two are coaxial. The current in the solenoid is ramped down to zero over a period of 0.3 s .


What average emf is induced in the second coil if it has a diameter of 3.8 cmand N = 6?

What is the induced emf if the diameter is 7.6 cm and N = 12?
