Question

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 0.225 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 0.60 s.

a) What average emf is induced in the second coil if it has a diameter of 4.1 cm and N = 9? Answer in units of uV.

b) What is the induced emf if the diameter is 8.2 cm and N = 18? Answer in units of uV.

Answer #1

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 0.225 AA . 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 0.6 s

A long, straight solenoid with a cross-sectional area
of 12.00 cm2 is wound with 80 turns of wire per centimeter, and the
windings carry a current of 0.16 A. A second winding of 10 turns
