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?

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 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 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
encircles the solenoid at its center. The current in the solenoid
is turned off such that the magnetic field of the solenoid becomes
zero in 0.08 s. What is the average induced electromotive force
(emf) in the second winding? ( ??=?? ? ??−??.?/? ) (?=?.??)

A 400 turn solenoid , 30 cm long has a diameter of 1.5 cm. A 20

A in 0.3 s, what will be the induced emf in the short coil during
this time?
