Problem
A sample of paramagnetic salt contains 2.0×1024 atomic dipoles each of dipole moment 1.5×10−23 JT −1 . The sample is placed under homogeneous magnetic field of 0.84 T and cooled to the temperature of 4.2 K. The degree of magnetic saturation achieved is equal to 15%. What is the total dipole moment of the sample for a magnetic field of 0.98 T and a temperature of 2.8 K (assume Curie's law)?
