A square, single-turn wire loop , 5 1.00 cm on a side is placed inside a solenoid that has a cir- cular cross section of radius r 5 3.00 cm, as shown in the end view of Figure P20.18. The solenoid is 20.0 cm long and wound with 100 turns of wire. (a) If the current in the sole- noid is 3.00 A, what is the flux through the square loop? (b) If the current in the sole- noid is reduced to zero in 3.00 s, what is the magnitude of the average induced emf in the square loop?

Question
A square, single-turn wire loop
, 5 1.00 cm on a side is placed
inside a solenoid that has a cir-
cular cross section of radius
r 5 3.00 cm, as shown in the
end view of Figure P20.18. The
solenoid is 20.0 cm long and
wound with 100 turns of wire.
(a) If the current in the sole-
noid is 3.00 A, what is the flux
through the square loop? (b) If the current in the sole-
noid is reduced to zero in 3.00 s, what is the magnitude of
the average induced emf in the square loop?
