A)

20.3 A/m
B)

1.5 A/m
C)

81.1 A/m
D)

40.6 A/m
E)

10.2 A/m

Question 2

A solenoid with n1 = 1200 turns/m and a current I1 = 2.5 A is filled with a paramagnetic material at a temperature T1 = 320 K.

A second solenoid with n2 = 1000 turns/m and a current I2 = 0.85 A is filled with the same paramagnetic material at a different temperature T2. The magnetizations are the same in both cases. What is the value of T2?
A)

256 K
B)

150 K
C)

67 K
D)

91 K
E)

201 K
