Figure 29.9
1) In Fig. 29.9, a bar magnet moves away from the solenoid. The induced current through the resistor
R
is:
A) zero
B) from
a
to
b
C) from
b
to
a
1)
2) A small square coil is located inside an ideal solenoid at the center with its plane oriented
perpendicular to the axis of the solenoid. The resistance of this coil is 2.00 Ω and each side is 4.00
cm long. The solenoid has 125 windings per centimeter of length. If the current in the solenoid is
increasing at a constant rate of 1.50 A/s, the current in the square coil is:
A) decreasing at 1.50 A/s
B) initially equal at 18.8 μA but is increasing
C) increasing at 1.50 A/s
D) steady at 18.8 μA
E) zero
