Halliday, Resnick & Walker — Maxwell's Equations; Magnetism of Matter: Problem 11

11 A sample of the paramagnetic salt to which the magnetization curve of Fig. 32-14 applies is to be tested to see whether it obeys Curie’s law. The sample is placed in a uniform 0.60 T magnetic field that remains constant throughout the experiment. The magnetization M is then measured at temperatures ranging from 10 to 300 K. Will it be found that Curie’s law is valid under these conditions?
