Aluminum has a magnetic susceptibility  = 1.7  10-5 at T = 300 K. What will be the magnetization of a small sample of aluminum placed in a 1.5 T magnetic field at T = 150 K?
 
  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
