- According to Figure 3, for μ = 14 × 10−5 henry/m, as the length of the solenoid increases, L:
A. increases only.
B. decreases only.
C. varies, but with no consistent trend.
D. remains the same.
- For a given solenoid length, what is the correct ranking of the values of μ in Figure 3, from the μ associated with the highest L to the μ
associated with the lowest L ?
F. 7 × 10−^5 henry/m, 14 × 10−^5 henry/m, 28 × 10−^5 henry/m
G. 14 × 10−^5 henry/m, 28 × 10−^5 henry/m, 7 × 10−^5 henry/m
H. 7 × 10−^5 henry/m, 28 × 10−^5 henry/m, 14 × 10−^5 henry/m
J. 28 × 10−^5 henry/m, 14 × 10−^5 henry/m, 7 × 10−^5 henry/m
- Based on Figure 2, a solenoid containing 100 coils with a magnetic field strength of 300 would most likely have been produced by a
current:
A. greater than 1.00 amps.
B. between 1.00 and 0.75 amps.
C. between 0.75 and .50 amps.
D. less than 0.50 amps.
